Skin Granulomas due to Mycobacterium gordonae

ABSTRACT: A 38‐year‐old woman presented with small, ulcerated, red or hluish nodules on the right hand, clinically resembling mycobacterial granulomas; these appeared a few months after a bite by a rat, while the patient was collecting frogs in a pond in the Belgian Ardennes. The histopaihologic picture was compatible with a diagnosis of mycohacterial infection and rare acid‐fast bacilli could be found. Repeated bacteriologic investigations were performed and these led to the identification of a strain displaying characteristics of My‐cobacterium gordonae. The skin condition responded well to rifampicin (300 mg/day) within 6 months.
