Disseminated Mycobacterium flavescens in a probable case of chronic granulomatous disease.

We report the case of a diabetic Chinese male with no previous history of recurrent infections. His course was at first notable for relapsing Salmonella blockley infections, following which he developed repeated soft-tissue infections and Cryptococcus neoformans pneumonia. He was diagnosed as having chronic granulomatous disease and was treated with gamma interferon. During the latter stages of his illness he developed Mycobacterium flavescens infection in soft tissues, joints, bones and lung. This is the first report of disseminated M. flavescens infection.
