This infection causes respiratory illness in birds, pigs, and humans, especially in immunocompromised people. These usually contain acid‐fast bacilli and have been reported in patients with HIV [35], following organ transplantation [36] and steroid therapy [37], and in Hodgkin's disease [38]. The commonest atypical mycobacterial skin infection is M. marinarum, which follows inoculation into superficial sites of injury after swimming in infected pools or immersion in aquaria. Immunopathogenesis and spectrum of infections in systemic lupus erythematosus. However, one case of skin infection with M. chelonae, also mimicking cutaneous vasculitis, was reported in a middle‐aged female with idiopathic multifocal uveitis being treated with steroids and immunosuppressants [10]. Subsequent biopsies taken for culture purposes showed a similar pattern, but no evidence of vasculitis was present. The lack of consensus on treatment is a reflection of the paucity of data derived from clinical trials. Of the oral antibiotics, sensitivity to ciprofloxacin and doxycycline is variable while tobramycin and imipenem are the parenteral agents of choice.

Cutaneous mycobacteriosis: analysis of 34 cases with a new classification of the disease. A reduced T-cell response, neutrophil dysfunction, diminished humoral immunity and decreased production of inflammatory cytokines [interleukin (IL) 1 and IL-6] in response to lipopolysaccharide stimulation make diabetic patients susceptible to infections [4, 5]. Often, ATM infections are not considered initially. Tenosynovitis due to Mycobacterium other than tuberculosis: a hazard of water sports and hobbies. What is it? Biopsy of the skin lesion demonstrated collections of neutrophil polymorphs surrounded by bands of granulomatous inflammation within the reticular dermis, which extended into underlying fat (Fig. Published by Oxford University Press. In contrast, atypical mycobacterial infections are much less common, with only rare case reports in SLE [7–9], but the present cases are the first reported instances of M. chelonae infection in SLE.

Cutaneous nodules of Mycobacterium Past history was insignificant with regard to acute emergencies requiring hospitalization. A complete neurological evaluation failed to reveal any neurodeficit. For the purpose of species determination, a polymerase chain reaction (PCR) of the isolated bacteria was undertaken. The histological spectrum of cutaneous mycobacterioses. NTMs are classified as rapid growers (mature growth within 3–7 days) or slow growers (mature growth in 2–3 weeks) [6]. There was no history of local trauma to the affected area. For example, atypical mycobacteria are widespread in the environment and are not pathogenic for guinea pigs, whereas M. tuberculosis is found only in humans and is highly pathogenic for guinea pigs.
