title: Pyoderma gangrenosum related to a new granulocyte colony-stimulating factor.
abstract: A 23-year-old Caucasian man diagnosed with stage IVB Hodgkin's disease was referred to a university oncology section after completing 1.5 cycles of chemotherapy. His chemotherapy consisted of doxorubicin HCL, bleomycin, dacarbazine, and vinblastine, with prophylactic administration of a granulocyte colony stimulating factor. He had developed postchemotherapy complications of possible cellulitis and necrotizing fasciitis that required wound debridement. The wound and tissue cultures were negative. Biopsies taken at the time revealed a dense inflammatory infiltrate consistent with an abscess. Over the course of 2 months, the wound healed with systemic antibiotics. The patient was reluctant to resume chemotherapy for his Hodgkin's disease because of his previous presumed skin infections. However, positive emission tomographic scanning revealed disease progression. Doxorubicin, bleomycin, dacarbazine, and prophylactic pegfilgrastim (a granulocyte colony-stimulating factor), were administered. Vinblastine was excluded from the new regimen. Shortly after chemotherapy and an injection of pegfilgrastim, the patient developed poorly defined, rapidly progressive erythema, edema, and pain in his right forearm. He presented to the emergency room, was evaluated by the orthopedics service, and taken to the operating room for debridement of suspected necrotizing fasciitis. When the dermatology service consulted the following day, the patient had developed an erythematous, edematous, tender plaque on his chest. After developing two additional lesions that began to ulcerate despite treatment with imipenem, vancomycin, clindamycin, rifampin, and gentamicin, the patient consented to a skin biopsy. His wound cultures continued to be negative.
