Mycobacterium (M.) marinum is a slow-growing
atypical mycobacterium found mainly in saltwater environments. Infection occurs following inoculation of a skin lesion and manifests as a localized granulo-ma; in fact, the most common cause of infection with M. marinum is the exposure of traumatized skin to affected aqueous environments (1), and it most commonly involves individuals with occupational and recreational exposure to non-chlorinated water (2)
