Mycobacterium marinum causes sporadic skin infection. It mostly appears on extremities with erythematous or bluish papule or nodule at the inoculation site, usually after skin abrasions are exposed to contaminated water or fish. A 43-year-old male patient with no prior medical history noticed the appearance of red lesions on the back of his left shoulder 2 years earlier. Various physicians visited the patient and misdiagnosed as contact dermatitis. Physical examination revealed polycyclic livid plaques with irregular hyperkeratosis on the back of his left shoulder. Eventually it was reported he carried a fishing net on his shoulder near the time lesions appeared. So, with suspicion of Mycobacterium marinum, skin biopsies were performed and histopathology showed epidermis with acanthosis and parakeratosis. The dermis showed severe infiltration of neutrophils and lymphoplasma cells with the presence of few giant cells and poorly defined granulomas indicating acute or chronic necrotizing granulomas. Within three weeks of starting treatment with oral clarithromycin, rifampin and co-trimoxazole, signs of improvement began. The manifestation of this disease and its site of involvement in this patient was very rare among previous case reports, so it was considered necessary to be reported.

“…The patient denied having any fish‐related puncture wounds but recalled handling fish without gloves while at work, in line with the Chinese custom of cooks handling the fish themselves. The clinical findings and histopathology of M. marinum infection are usually non‐specific, making the medical history of patients – including their occupation and exposure history – essential for diagnosis 4 …”

Clinical manifestation and incubation period are heterogeneous depending on modality of mycobacterial acquisition, bacterial load and virulence and host immune status [ 55 ]. Immunocompromised individuals are more susceptible to less pathogenic NTM (i.e.…”

Purpose of review The aim of this article is to review the most recent evidences concerning mycobacterial skin infections, limiting the period of literature research to 2020--2021. Recent findings Mycobacterial skin infections include a heterogeneous group of cutaneous diseases. Cutaneous tuberculosis is usually the result of hematogenous dissemination or spread from underlying foci and it must be distinguished from tuberculids, resulting from the immunological reaction to Mycobacterium tuberculosis antigens. Leprosy prevalence was drastically reduced after introduction of multidrug therapy in the 1980 s, but cases are still reported due to underdiagnosis, and animal and environmental reservoirs. Recent advances concentrate in the diagnostic field. Specific guidelines for the treatment of nontuberculous mycobacteria skin infections are missing and surgical procedures may be required. Prognosis is better as compared to nontuberculous mycobacteria lung disease. Rapid laboratory-confirmed diagnosis of Buruli ulcer may be achieved by the IS2404 PCR. Among new drugs, telacebec is promising in terms of potency, shorter duration and tolerability in animal studies. A clinical trial in humans is planned. Summary Mycobacterial cutaneous lesions are nonpathognomonic and clinical suspicion must be confirmed by culture or molecular detection. Long-course multidrug treatment is required based on susceptibility tests. Surgical intervention may also be required. Rehabilitation and psychosocial support reduce long-term physical and mental consequences mostly in Buruli ulcer and leprosy.
