A case of a gonococcal pustule of the finger with lymphangitis and regional adenopathy is described. Gram stain, culture, and fluorescent antibody staining confirmed the diagnosis. A traumatic break in the skin was the portal of entry for the organisms. Digital-genital contact with an infected sexual partner was the presumed mode of acquisition of the infection. The patient showed no evidence of urethritis. The lesions readily resolved with parenteral penicillin therapy.
