Penile ulcer in heroin abuse: a case report.

The rarity of reported cases of cutaneous ulcerations in heroin abusers prompts this report of a 25-year-old man with a painless, slightly necrotic and purulent ulcer of the dorsal shaft of the penis. The differential diagnosis of the lesion and cutaneous manifestations of heroin abuse are reviewed. To our knowledge, this is only the second reported case of penile ulcer from heroin injection.
