A case of granulomatous skin lesions caused by Mycobacterium marinum in the Campania region.
The diagnosis of cutaneous Mycobacterium marinum infection is frequently presumptive, as detection by conventional methods is difficult. We describe a patient with granulomatous skin lesions on the right dorsal hand and forearm. Histological examinations were presumptive for mycobacterium lesions. We identified Mycobacterium marinum directly in the patient's lesional skin biopsy combining polymerase chain reaction (PCR) amplification using Mycobacterium genus-specific primers, and subsequent restriction enzyme analysis enabling identification to the species level. The symptoms were no longer present after specific therapy, thereby confirming the initial diagnosis.
