A 27-year-old man presented with a swollen penis 1 week after being bitten by his girlfriend during a sexual act. There were no associated urinary symptoms. Examination under anaesthesia revealed a severe inflamed prepuce with ulcers on the undersurface of the prepuce and purulent discharge. After taking pus for culture and sensitivity, circumcision was carried out under antibiotic cover. Pus culture showed growth of mixed anaerobes. The patient made an uneventful recovery and was discharged after 48 hours. Histology revealed multiple ulcers with infiltration of acute and chronic inflammatory cells in subcutaneous connective tissue.
