Mycobacterium phlei infection of the foot: a case report.

A case of Mycobacterium phlei infection in the flexor digitorum longus and posterior tibialis tendon of an otherwise healthy adult male is reported. To our knowledge, this is the second reported case in the English literature of human infection by M. phlei. Diagnosis and treatment of nontuberculous mycobacterial infection are discussed. The clinician is encouraged to include this infection in the differential diagnosis of pain and swelling in the extremity.
