BACKGROUND: Sebaceous nevus is a benign congenital epidermal nevus. Its association with basal cell carcinoma is well known. METHOD: This is a case report of sebaceous carcinoma complicated by both basal cell carcinoma and squamous cell carcinoma. RESULTS: The behavior of this tumor is very aggressive, resulting in poor prognosis. CONCLUSIONS: All sebaceous nevi should be excised early.
