Blistering distal dactylitis in an adult.

Streptococci are responsible for a diverse spectrum of cutaneous infections like erysipelas, impetigo, and cellulitis. Blistering distal dactylitis is an infrequent, superficial infection of the anterior fat pad of the distal portion of the finger described classically in children. We report a case of blistering distal dactylitis in an adult caused by group A beta-hemolytic streptococci that was cured with oral phenoxymethyl penicillin. Familiarity with blistering distal dactylitis should permit the dermatologist and internist to diagnose this new entity in adults.
