“…It spreads through the distribution of the lymphatic system and can infect both immunocompetent and immunocompromised individuals. 4 The clinical manifestations of M. marinum include granulomatous skin and soft tissue lesions, especially in acral distribution with nonspecific and erythematous nodules, papules, and plaques, which makes the diagnosis with other granulomatous lesions more difficult. 5 Laboratory and pathology evaluations are essential to make a definite diagnosis.…”

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.

“…Cutaneous infections caused by Mycobacterium marinum (Mma), a member of the nontuberculous mycobacteria (NTM) group, is a rare disease. M. marinum virtually always causes cutaneous disease through direct inoculation, typically following traumatic injuries caused by a contaminated environmental source 1,2 .…”

“…Among non-tuberculous mycobacterial infections, M. marinum is the most common (about 45% of cases). 1 The infection is caused by contact with infected water or fishes through minimal skin trauma.…”

“…The incubation period is approximately 2 to 3 weeks, and the causative agent of human infection is lethal for animals; in fact, some patients report the onset of the lesion concurrently with the death of infected fishes. 1 Based on the clinical aspect and the infiltration of deep tissues, skin lesions are classified into four types: (a) papules/nodules and patches with erosion an ulceration, (b) more than one lesion with a sporotrichoid pattern, (c) deep tissue infection, and (d) systemic disease. 2 Some authors report an eczematous-like presentation with the involvement of fingertips.…”
