A case of Microbacterium (M) marinum skin infection in a 19-year old woman is reported. Clinical lesions, characterized by brownish painful nodules localized on the left hand and arm, were preceded by a perionixis of the 3rd left finger. Histologic examination showed a tuberculoid granuloma without alcohol-acid fast bacilli. A positive culture for M marinum was obtained. The patient had cleaned her tropical fish tank some days before the eruption of the first nodule. The patient was treated successfully with rifampicin plus doxycycline. In this case the perionixis was probably the portal of entry for atypical mycobacteria.
