Finally, M. chelonae is often susceptible to macrolides, cefoxitin, fluoroquinolones, and tobramycin (1, 42). ASM journals are the most prominent publications in the field, delivering up-to-date and authoritative coverage of both basic and clinical microbiology. Some individuals may manifest with a single lesion, but others manifest with multiple lesions, depending on the mode of acquisition and level of host immunity (42, 117). 1). Efficacy and Mechanisms of Flavonoids against the Emerging Opportunistic Nontuberculous Mycobacteria. Keywords: (Lon), F.F.T.M R.C.P.S. The treatment for cutaneous mycobacterial infections depends on the specific pathogen and therefore requires a careful consideration of antimicrobial choices based on official treatment guidelines. In this review, we group cutaneous mycobacterial infections into four major categories: (i) infection due to Mycobacterium tuberculosis complex, (ii) infection caused by Mycobacterium leprae and M. lepromatosis, (iii) infection caused by Mycobacterium ulcerans and other slowly growing mycobacteria (SGM), and (iv) infection due to rapidly growing mycobacteria (RGM). Ecological data suggest that environmental factors, such as trauma or skin breaks during soil and water exposures, insect vectors, free-living amoebas, and animal reservoirs (e.g., armadillos, squirrels, felines, or other animals), influence leprosy transmission (39, 47, 49–63). Dr. Franco-Paredes obtained his medical degree from L Salle University in Mexico City. MAC bacteria do not make … Dermatologic surgery 28.8 (2002): 768-771. An adult with Mycobacterium abscessus infection presenting as scrofuloderma with extensive tissue destruction in the right cervical and supraclavicular areas. Along with Mycobacterium fortuitum and Mycobacterium chelonae, members of the M. abscessus complex (M. abscessus, Mycobacterium massiliense, and Mycobacterium bolletii) are the major NTM associated with cutaneous involvement (Fig. The most common sites of involvement are the neck, axillae, or groin (Fig. They share phenotypic and genotypic features, including the large virulence plasmid (pMUM) required for mycolactone production. We have no conflicts of interest to disclose. Roughly 75,000 - 105,000 people will be … This clinical form presents predominantly in children, but when it is present in adults, it tends to occur among those with occupational exposures, such as butchers or farmers. Treatment of cutaneous TB follows the same recommendations as for other forms of TB, with multidrug therapy (MDT) and ideally adjusted by culture and susceptibility data (47, 67, 69). That is a blessing and a curse. Mycobacterium kansasii leading to a sporotrichoid nodular lymphangitis of the right arm. The management of leprosy requires the use of MDT in combination with steroids or other anti-inflammatory drugs among those with leprosy reactions (72, 74, 78). These topics have been dealt with elsewhere in the CDS. Characteristic sporotrichoid nodular lymphangitic spread…. The differential diagnosis of this condition includes paracoccidioidomycosis, syphilis, lymphogranuloma venereum, pyoderma gangrenosum, and skin malignancies (47, 69). 2010 Jan;28 Suppl 1:46-50. doi: 10.1016/S0213-005X(10)70008-2. Innate immune responses by macrophages in human tissues are responsible for initiating nerve damage in leprosy by interaction with phenolic glycolipid 1 (PGL-1) with myelinating glia (88, 89). The domestication of animals and the development of water distribution systems also influenced the transmission dynamics of mycobacterial infections (16). Skin biopsies of cutaneous lesions to identify acid-fast staining bacilli and cultures represent the cornerstone of diagnosis. A similar mechanism of transmission maybe responsible for some cases of leprosy (33). This progressive clinical form originates through lymphatic spread or by contiguous spread from a lymph node or bone (47). Clinically, cutaneous mycobacterial infections present with widely different clinical presentations, including cellulitis, nonhealing ulcers, subacute or chronic nodular lesions, abscesses, superficial lymphadenitis, verrucous lesions, and other types of findings. He completed an internship and residency in internal medicine at the University of Texas Health Science Center, followed by a fellowship in infectious diseases at Washington University. Mycobacterium avium complex (MAC) refers to infections caused by two types of bacteria: Mycobacterium avium and Mycobacterium intracellulare. Culturing M. ulcerans is cumbersome since it requires a low oxygen concentration and a temperature between 29°C and 33°C. Copyright © 2018 American Society for Microbiology. Recent studies have demonstrated that the prevalence of nontuberculous mycobacterial infections is increasing in many settings (24–28). Cutaneous involvement of M. kansasii is usually present in immunocompromised hosts and sometimes with concomitant pulmonary disease or disseminated disease (24, 37). Currently, most cases of Buruli ulcer occur in parts of western and central Africa, but cases occur in at least 33 countries, mostly in South America and Western Pacific regions (110). Most of these presentations occur in the extremities, particularly over joints. The histopathology of BU demonstrates large numbers of extracellular bacilli during the acute phase of infection (24, 47, 109). 2010 Oct;23(5):445-55. doi: 10.1097/QCO.0b013e32833c2209. Since the early 1980s, multidrug therapy (MDT) has been universally instituted through active case finding in highly affected communities. Rapidly growing mycobacteria, including the Mycobacterium abscessus group, Mycobacterium chelonei, and Mycobacterium fortuitum, are increasingly recognized pathogens in cutaneous infections associated particularly with plastic surgery and cosmetic procedures. Lupus vulgaris is a chronic form of cutaneous TB that may occur due to regional lymphatic or hematogenous spread in individuals with reinfection or reactivation of latent TB infection or BCG vaccination (47, 69, 71). The pathogenesis of cutaneous mycobacterial infections is the result of hematogenous dissemination, local or regional spread from a deep-seated infection, or direct inoculation into the skin and soft tissues (24). Among patients with advanced immunosuppression, Mycobacterium kansasii, the Mycobacterium avium-intracellulare complex, and Mycobacterium haemophilum may cause cutaneous or disseminated disease. Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. This organism preferentially grows at 30°C, explaining its predilection for causing lesions in the upper and lower extremities (34–36). The most notable mycobacterial infections are those that are caused by Mycobacterium tuberculosis complex and Mycobacterium leprae. These events include waves of human expeditionary, military, or commercial migrations (8). 2000. pp. MAC is composed of several different slowly growing mycobacterial species, including M. avium, M. intracellulare, Mycobacterium indicus pranii, Mycobacterium chimera, Mycobacterium arosiense, and many others. See this image and copyright information in PMC. Disease caused by M. marinum is associated with minor to moderate skin infections presenting as granulomatous lesions similar to those caused by M. tuberculosis or M. haemophilum. Lupus vulgaris may occur concomitantly with scrofuloderma, or it rarely may be associated with primary-inoculation TB. Results The medical records of 63 patients with skin or soft tissue infections due to rapidly growing mycobacteria were reviewed. These infections are increasing at about 8% each year. He is also the Associate Director for Research for the Global Health Institute at Stony Brook University. The precise mode of transmission of leprosy remains uncertain but probably involves human-to-human contact through respiratory droplets (29, 30, 45–47) or through blood transfusion (48). This clinical form affects women predominantly and manifests as smoldering nodules and annular plaques, or it may present with hypertrophic or vegetative lesions. Mycobacterium marseillense is a member of the M. avium complex that has caused infections with lymphatic or pulmonary involvement sporadically in humans (2–4).We report M. marseillense infection involving facial skin … Clinical manifestations of leprosy: borderline tuberculoid (BT) (A), borderline borderline (BB) (B), and lepromatous (LL) (C). The clinical diagnosis of leprosy relies on the identification of characteristic plaques, macules, or nodules concomitantly with sensory loss in the form of hypoesthesia or anesthesia and the presence of thickened nerves (72, 74). (21, 22). HIV coinfection/AIDS appears to foster the rapid progression of lesions into severe ulcerative stages (31, 109). 2) (47, 69). Learning objectives. Mycobacterium kansasii leading to a sporotrichoid nodular lymphangitis of the right arm. Additionally, histopathological evaluation of skin biopsy specimens may be useful in identifying leprosy, Buruli ulcer, and cutaneous tuberculosis. Localized cutaneous infections are due to posttraumatic wound infection, catheter-associated infections (e.g., from peritoneal dialysis or central venous catheters), postsurgical infections, and trauma-associated infections (Fig. Leprosy reactions, due to their potential inflammatory compromise of the nerve fibers, lead to sensory and motor loss (85, 90–92). Among patients with relapse, some researchers have detected drug resistance with the use of rapid DNA-based molecular assays (99). Cutaneous forms of TB are currently classified according to clinical morphological patterns, the route of acquisition (exogenous inoculation, hematogenous spread, or regional extension), and the host immune status (47, 64–66, 71). M. chelonae and M. abscessus usually present with multiple skin lesions, while M. fortuitum tends to present as a single lesion (24, 42, 43, 117). NTM infections of the skin may spread to cause tenosynovitis, myositis, osteomyelitis, and septic arthritis (24, 42, 117). Dermatol Clin. The clinical spectrum of disease associated with mycobacterial pathogens depends on the route of exposure and host susceptibility factors (25–27). (Slightly dated but comprehensive and provides a table of cutaneous and extracutaneous manifestations of infection of each organism, as well as a table detailing the growth characteristics of each of the mycobacterial … Early identification of new cases likely prevents further transmission, but, importantly, it may also reduce the risk of neurological dysfunction and disability associated with leprosy (96–98). Patients with M chelonae or M abscessus were older … 2020 Sep 9;8(9):1380. doi: 10.3390/microorganisms8091380. Wilmer E. Villamil-Gómez, M.D., Ph.D.(c), is a medical doctor (graduated from the University of Cartagena), family medicine specialist (University of Cartagena), specialist in epidemiology (School of Medicine, Juan N Corpas University), candidate for Ph.D. in tropical medicine and infectious diseases (University of Cartagena and University of the Atlantic), and fellow in infectology (University of Buenos Aires). Untreated primary-inoculation TB may resolve in a period of 12 months or longer or may progress to disseminated forms of the disease by hematogenous spread of the bacillus to other organs. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Antibiotics (Basel). Clinical manifestations of leprosy: borderline tuberculoid (BT) (A), borderline borderline (BB) (B), and lepromatous (LL) (C). In 2016, he edited a textbook, Neglected Tropical Diseases in Latin America and the Caribbean (Springer-Verlag), and he has written a textbook on infectious diseases (Core Concepts in Clinical Infectious Diseases [Elsevier]). Because its optimal temperature for growth is around 30°C, cutaneous lesions most frequently occur in the upper or lower extremities and sometimes in the tip of the nose. chelonae [3†]. Usually occur on the arms or knees. Cutaneous tuberculosis exhibits different clinical phenotypes acquired through different routes, including via extrinsic inoculation of the tuberculous bacilli and dissemination to the skin from other sites, or represents hypersensitivity reactions to M. tuberculosis infection. Eduardo Liceaga.” He is also a Researcher of the Health Systems, Health Secretary, Mexican Government, and Senior Researcher of the National System of Researchers (CONACYT). These organisms are characterized by their staining and are identified as acid fast bacilli. The WHO recommended the institution of multidrug therapy with dapsone, rifampin, and clofazimine in 1982 (47, 97, 99). Relapse or reinfection is considered a rare clinical phenomenon (47, 78, 86, 87). The molecular mechanisms by which M. tuberculosis and M. leprae have evolved to cause disease involved complex interactions between the pathogen and the host. Other diseases that need to be considered in the differential diagnosis include bartonellosis, tularemia, leishmaniasis, syphilis, eumycetoma, and yaws (47, 69). Created 2008. Susceptibilities to antimicrobials depend on the species.

However, it is important to confirm the detection of inducible macrolide (clarithromycin) resistance by the presence of the erm41 gene (1, 117, 118). In addition, Dr. Henao-Martínez directs the Outpatient Infectious Diseases Rotation for the internal medicine and preventive medicine residency programs. Infiltrated erythematous plaque with yellowish scales and crusts (A) resolved to a scar after clearance of infection … Other environmental mycobacteria can produce the lipid toxin mycolactone (111, 113). Mycobacterial infections are a group of multisystem infections caused by the members of the family Mycobacteriaceae. He is the Director of the Tick-Borne Disease Center at Stony Brook. Skin infections may clear up without treatment. Depending on the BCG vaccination status, tuberculin skin testing using purified protein derivative has a specificity of 63% and a sensitivity between 33 and 96% for cutaneous tuberculosis (47, 72). In many individuals, pathogenic mycobacterial species may breach our first-line barrier defenses of the innate immune system and modulate the activation of phagocytes to cause disease of the respiratory tract or the skin and soft tissues, sometimes resulting in disseminated infection.  |  Untreated cases or those with extensive and deep ulcerations develop scarring contractures, deformity, osteonecrosis, and limb loss (31, 109). BU is considered a neglected tropical disease (NTD) because most cases occur among impoverished populations, often causing an important disability burden (2, 15, 31, 32, 109). Patients with M. haemophilum may also experience immune reconstitution events analogous to leprosy reactions or to paradoxical immune reactions seen after initiating antimycobacterial therapy in patients with M. tuberculosis infection (35, 36, 119). massiliense among patients with cystic fibrosis (43, 44). Further clinical and epidemiological research that advances our understanding of mycobacterial pathogens that infect the skin and soft tissues may improve our ability to prevent these infections and optimize their medical management. Atypical mycobacterial infections are infections caused by a species of mycobacterium other than Mycobacterium tuberculosis, the causative bacteria of pulmonary TB and extrapulmonary TB including cutaneous TB; and Mycobacterium leprae, the cause of leprosy.. Atypical mycobacteria may cause many different types of infections… Mycobacterium peregrinum is a rapidly growing mycobacterium (RGM) that rarely causes skin infections. Compared to bacterial skin infections, mycobacterial skin infections occur rarely. In a period of approximately 4 weeks, the nodule, plaque, or edematous area evolves into an ulcer with undermined borders. Some patients may have associated erythema nodosum. Andrés F. Henao-Martínez, M.D., graduated from Universidad del Valle, School of Medicine, in Colombia in 2003. Would you like email updates of new search results? He has been the director of the travel clinic at University of Colorado Hospital since 2016. Risk factors for acquiring major nontuberculous mycobacterial infections of the skin and soft tissues and medical and surgical recommendation. However, NTM are becoming important emerging pathogens in different geographical areas. [] Although the prevalence of MAI infection has increased following the epidemic of acquired immunodeficiency syndrome (AIDS), MAI infection remains a rare cause of skin … Mycobacterium haemophilum is a nontuberculous mycobacterium that causes skin, joint, bone, and pulmonary infections in immunocompromised persons and lymphadenitis … The sites most frequently affected include the lower extremities or buttocks in tropical and subtropical settings, whereas in temperate areas lesions occur most frequently in the head and neck. He also obtained a Masters in Public Health in Global Health from the Rollins School of Public Health of Emory University. Visceral tuberculosis (pulmonary or extrapulmonary) is rarely associated with concomitant cutaneous involvement (68). Alternatively, a combination of rifampin and clarithromycin or rifampin and moxifloxacin could be used (109, 112). In England, Ireland, and Scotland, red squirrels may be infected and develop leprosy-like lesions due to M. lepromatosis (53). On rare occasions, outbreaks of nontuberculous mycobacterial (NTM) skin infections have been reported after tattooing (2,3). The diagnosis of BU maybe confirmed by direct microscopy of suspicious lesions, histopathology of skin biopsy specimens, culture, and IS2404 PCR (PCR) (24, 31, 109). An 11-year-old male demonstrating a destructive panniculitis causing ulceration with undermined borders, characteristic of Buruli ulcer. He has authored more than 350 peer-reviewed publications on infectious diseases and tropical medicine. Tuberculids are cutaneous disorders that represent hypersensitivity reactions to mycobacterial antigens. The number of new cases will reach the 4 million mark by 2020 (since 2000) (76). In 1947, Mycobacterium ulcerans was identified as the cause of Buruli ulcer (BU) (2, 3, 31, 32, 109–111). Comparison of epidemiological and clinical features of the four categories of cutaneous mycobacterial infections: cutaneous tuberculosis, leprosy, Buruli ulcer, and disease caused by nontuberculous mycobacteria. Lesions of lupus vulgaris may have the appearance of “apple jelly” on diascopy (47, 69, 71). Chau, C. L. F., et al. The most important conditions that should be considered in the differential diagnosis of BU include tropical phagedenic ulcers, cutaneous tuberculosis, vascular (venous or arterial) ulcerations, diabetic foot ulcerations, pyoderma gangrenosum, infections due to Haemophilus ducreyi, cutaneous leishmaniasis, ulcerative yaws, fungal infections (e.g., chromoblastomycosis), and pyogenic ulcerations (e.g., caused by Staphylococcus aureus) (24, 109, 112). Members of the M. abscessus complex tend to be susceptible to macrolides, amikacin, cefoxitin, and imipenem (115). Clinically, BU affects predominantly the lower extremities (>55%) and less often the upper extremities or other body parts (31, 109, 111, 112) The toxin (polyketide), mycolactone secreted by M. ulcerans causes tissue destruction (111, 113), local immunosuppression through the inhibition of protein translocation into the endoplasmic reticulum of cytokines of the innate immune system, membrane receptors, adhesion molecules, and T-cell-dependent cytokines (114). 2015 Jul;33(3):563-77. doi: 10.1016/j.det.2015.03.017. This strain of M. lepromatosis appears to have diverged from the two human strains from Mexico (53). The entry of the M. leprae bacillus into the Schwann cell activates the cell to enter into a dedifferentiation process. Mycobacteria may seed the skin and soft tissues during systemic dissemination in immunosuppressed individuals (24, 25, 37, 42–44). Mycobacterium ulcerans produces a mycolactone toxin that leads to subcutaneous tissue destruction and immunosuppression, resulting in deep ulcerations that often produce substantial disfigurement and disability. Clinical studies need to determine whether differences between infection with M. leprae and M. lepromatosis are clinically distinguishable (102, 107, 108) or whether coinfection with M. leprae and M. lepromatosis may potentially predispose individuals to experience more severe leprosy reactions (108). Rapid diagnostic tests to detect mycolactone are currently under evaluation for use as point-of-care tests in areas of high endemicity (109). Mycobacterium ulcerans produces a mycolactone toxin that leads to subcutaneous tissue destruction and immunosuppression, resulting in deep ulcerations that often produce substantial disfigurement and disability. Mycobacterial Species as Human PathogensThe genus Mycobacterium is part of the order Actinomycetales and the phylum Actinobacteria and belongs to a variety of environmental habitats, including natural waters, soils, and drinking water distribution systems (1, 20–23). Mycobacterium marinum, a close relative of M. ulcerans, is an important cause of cutaneous sporotrichoid nodular lymphangitic lesions. Geography-based environmental exposures influence the epidemiology of cutaneous mycobacterial infections. Carlos Franco-Paredes, M.D., M.P.H., is an infectious diseases clinician with expertise in tropical medicine and neglected tropical diseases. Skin and soft tissue infections are the most common pre-sentation for the rapid-growing speciesMycobacterium fortuitum, M. abscessus,andM. The modes of transmission of the different mycobacterial species involved in cutaneous disease include zoonotic transmission (e.g., foodborne transmission of Mycobacterium bovis by ingestion of unpasteurized dairy products) (16, 23), person-to-person transmission (e.g., of leprosy) (29, 30), vector-borne transmission (possibly for Mycobacterium ulcerans) (3, 31–33), and acquisition of infection from environmental exposures (e.g., freshwater or salt water injuries leading to Mycobacterium marinum, M. ulcerans, or Mycobacterium haemophilum infection) (24, 33–38) (Table 1). The most common clinical presentations of mycobacterial infections include pulmonary, cutaneous and disseminated forms in immunocompromised hosts. We report here 5 patients with cutaneous and/or soft tissue infection … The treatment for cutaneous mycobacterial infections depends on the specific pathogen and therefore requires a careful consideration of antimicrobial choices based on official treatment guidelines. Most cases of cutaneous infections take place among individuals who suffered puncture injuries or other types of trauma in freshwater or salt water. The lesions originate from autoinoculation of the mucosal orifices by other cutaneous draining sites from internal organ infections. Similarly, acute military tuberculosis represents primary infection in individuals with advanced immunosuppression, including those with HIV infection/AIDS (71). In many individuals, pathogenic mycobacterial species may breach our first-line barrier defenses of the innate immune system and modulate the activation of phagocytes to cause disease of the respiratory tract or the skin and soft tissues, sometimes resulting in disseminated infection. Mycobacterium chelonae is a rapidly growing non-tuberculous mycobacterium, which causes infections of the human skin and soft tissue. HHS 1996 Dec;11(4):244-51. Identifying M. tuberculosis in tissue specimens through culture or molecular detection is of paramount significance when suspecting most clinical forms of cutaneous tuberculosis. Thank you for sharing this Clinical Microbiology Reviews article. Tuberculosis verrucosa cutis of the hand, manifesting as verrucous plaques caused by direct inoculation of the tuberculous bacilli into the skin of an individual previously sensitized to this pathogen. Historically, NTM were classified according to the Runyon classification based on their growth rates and their ability to produce pigment in response to light (1, 115). The diagnosis of mycobacterial infections of the skin and soft tissues requires a low threshold of clinical suspicion given the broad spectrum of potential clinical presentations. Tuberculosis verrucosa cutis of the hand, manifesting as verrucous plaques caused by direct…, Scrofuloderma presenting in the neck, resulting from direct extension of an infected left…, Clinical manifestations of leprosy: borderline…, Clinical manifestations of leprosy: borderline tuberculoid (BT) (A), borderline borderline (BB) (B), and…, An 11-year-old male demonstrating a destructive panniculitis causing ulceration with undermined borders, characteristic…, An adult with Mycobacterium abscessus infection presenting as scrofuloderma with extensive tissue destruction…, Infection caused by Mycobacterium fortuitum…. This infection may present as a localized or disseminated disease in immunocompromised hosts, including those with HIV infection/AIDS, transplant recipients, and those receiving biological agents such as anti-TNF-α agents (119). The diagnosis of Buruli ulcer is mostly a clinical one and is based on the age of presentation, geographic area, and location (31, 109, 112). New cutaneous lesions presenting during or after completing MDT are most likely caused by leprosy reactions (47, 85, 91, 92). Classification of major pathogenic mycobacteria. However, when it occurs, it is usually in the form of scrofuloderma or lupus vulgaris (47, 67–70). This article reviews the dermatologic manifestations of Mycobacterium avium-intracellulare (MAI, or MAC) infection.. MAI is an opportunistic pathogen that usually causes disease in the weakened immune system. Human Societies and the Origin and Spread of Major Mycobacterial PathogensMycobacteria are aerobic rod-shaped bacteria that do not form spores and that are lipid rich with long-chain mycolic acids in their cell walls, which are largely responsible for their acid fastness (1). of woman with Mycobacterium marseillense skin infection, China, 2018, and genomic analysis of isolate. He is a member of multiple national and international associations in dermatology, medical mycology, and tropical medicine (especially in mycetoma, chromoblastomycosis, sporotrichosis, mucormycosis, superficial cutaneous mycoses, mycobacterial infections, leprosy, and cutaneous parasitoses). M. kansasii has been identified only in municipal water systems (21, 22, 42). The most frequent sites of involvement include the fingers and dorsum of the hands, followed by ankles or buttocks (Fig. In the human host, mycobacterial infections may affect many anatomical sites, but since they enter through the skin and mucosal barriers, they lead mostly to pulmonary or cutaneous infections (25–28). An adult with Mycobacterium abscessus infection presenting as scrofuloderma with extensive tissue destruction in the right cervical and supraclavicular areas. The infection may then be carried to other sites by immature cells (83, 84). He is the former director of the Tropical Medicine Institute “Alexander von Humboldt” and Professor of Medicine and Infectious Diseases at Universidad Peruana Cayetano Heredia in Lima, Peru. Cutaneous mycobacterial infections may cause a wide range of clinical manifestations, which are divided into four main disease categories: (i) cutaneous manifestations of Mycobacterium tuberculosis infection, (ii) Buruli ulcer caused by Mycobacterium ulcerans and other related slowly growing mycobacteria, (iii) leprosy caused by Mycobacterium leprae and Mycobacterium lepromatosis, and (iv) cutaneous infections caused by rapidly growing mycobacteria. Dr. Franco-Paredes has an adjunct faculty appointment as a research professor at the Hospital Infantil de Mexico Federico Gomez in Mexico City. Infection caused by M. lepromatosis is responsible for this unique clinicopathological presentation, which is known as Lucio’s phenomenon (101, 102, 104, 106–108). Tuberculosis cutis orificialis occurs among severely immunocompromised middle-aged and older adults with advanced pulmonary, gastrointestinal, or genitourinary tuberculosis (47). Most infections occur following skin … The clinical spectrum of cutaneous manifestations of M. haemophilum includes multiple skin lesions presenting as erythematous or violaceous papules, plaques, or nodules. Treatment guidelines recommend performing susceptibility testing of mycobacterial isolates with the goal of optimizing the choice of specific antimycobacterial drug combinations, since the MIC to specific antimicrobials correlates clinically with in vivo responses to antimicrobial therapy for many mycobacterial species (1, 42). Category II is defined by the presence of nonulcerative or ulcerative plaques and edematous forms (Fig. His H index is currently 24. Despite an increasing incidence of such infections, patients are often misdiagnosed. Molecular identification of M. ulcerans by employing quantitative PCR (qPCR) assays is an alternative methodology for confirming a diagnosis of Buruli ulcer. Epub 2015 May 8. Surgical debridement and skin grafting are used to speed wound healing in those with large lesions. This form is also known as tuberculosis colliquative cutis.
