Mycobacterium marinum with associated bursitis.
BACKGROUND
Mycobacterium marinum infections have been reported for over 50 years, mostly in association with trauma in the setting of water exposure.


OBJECTIVE
The differential diagnosis for nodules in a sporotrichoid distribution with simultaneous bursitis is discussed. Mycobacterium marinum treatment regimens for skin and joint involvement are reviewed.


METHODS
Mycobacterium marinum was identified by skin tissue culture with Lowenstein-Jensen medium at 32 degrees C. Histopathologic findings support mycobacterial infection.


RESULTS
Bursitis and nodules resolved in the first 2 months of a 6-month course of minocycline treatment.


CONCLUSIONS
Bursitis is an extremely rare but significant complication of M. marinum.
