ABSTRACT

Sebaceous carcinomas of the skin are rare tumors. They most often occur on the skin of the head and neck. Their clinical diagnosis is difficult and the evolution is unpredictable. Recurrence and metastasis are not rare. Treatment of choice is large surgical excision. Opinions are divided regarding the use of chemotherapy and radiotherapy. A case of cutaneous sebaceous carcinoma on the right side of the nose that occurred on a previously irradiated skin is described, with rapid metastasis to the right paramandibular region.
