Primary cutaneous small-cell carcinoma: a case report.

Most commonly arising in the gastrointestinal and genitourinary tracts, extrapulmonary small-cell carcinoma is quite rare. Although its prognosis is very poor, complete remission or even cure can be achieved by combination of different treatment modalities. We report here a 32-year-old woman with a cutaneous gluteal mass diagnosed as small-cell carcinoma of the skin. Combination chemotherapy containing cisplatin and etoposide was started. Radiotherapy was administered after two courses of chemotherapy. Following radiotherapy, additional 4 courses of chemotherapy were given. She has been in remission for three years with no evidence of tumor recurrence.
