  • Review of nine culture-positive cases of Mycobacterium marinum infection revealed a broad range in the histopathologic features of lesions produced by this organism. Four synovial lesions and five cutaneous infections were observed. A range of inflammatory changes were seen in both synovial and skin lesions, varying from mostly acute inflammation with suppuration to a more chronic process with numerous, well-formed granulomas. Organisms were observed in the biopsy sections of only one of the nine cases. Therefore, culture of the biopsy tissue at 30 degrees C is crucial in establishing the diagnosis. These cases emphasize the importance of considering mycobacterial infection and performing cultures even when granulomatous changes in the synovium or skin are subtle.
