[Atypical mycobacterial infection due to Mycobacterium fortuitum]

The case is presented of a 48-year-old woman who, in association with repeated septic temperatures, developed abscesses in the region of the right shoulder and in the right ankly. Histological examination from excisates revealed caseous tuberculoid granulomas. Mycobacterium fortuitum was isolated from the pus of both abscesses. Although the Mycobacterium fortuitum was resistant to nine commonly used tuberculostatics, it was found to be sensitive to ethionamide and capreomycine. The use of these two drugs in combination with local measures proved successful.
