Bleomycin sulfate, administered parenterally alone and in combination with vinblastine sulfate for treatment of various neoplastic diseases, has been associated with the development of Raynaud's phenomenon (1-5). Additionally. bleomycin therapy has been associated with a number of varied skin reactions, including hyperpigmentation, sclerosis, gangrene, indurated plaques, and hyperpigmented nodules (6).Several recent reports have described the use of intralesional injections of bleomycin sulfate for treatment of cutaneous warts, and have noted no complications (7-10). We describe a patient who received this treatment and subsequently developed Raynaud's phenomenon, which was limited to the injected digit.Case report. A 23-year-old, healthy woman sought medical treatment for a wart located over the palmar aspect of the proximal interphalangeal joint (PIP) of the right index finger. An initial, unsuccessful, attempt at electrocautery was followed by multiple local liquid nitrogen treatments over the ensuing 5 months; each treatment was unsuccessful. Four months later, after regrowth of the wart, the patient received a single injection of bleomycin sulfate (1 mg)
