We report a case of primary epidermoid carcinoma of the frontal sinus associated with cholesteatoma. We postulate that the carcinoma is secondary to malignant degeneration of the cholesteatoma. The literature review revealed 38 cases of cholesteatoma of the frontal sinus. Four were associated with carcinoma. To the best of our knowledge, this is the fifth such case in the world literature.
我们报告一例伴有胆脂瘤的额窦原发性表皮样癌。我们推测该癌是胆脂瘤恶变所致。文献回顾显示有38例额窦胆脂瘤病例。其中4例伴有癌症。据我们所知，这是世界文献中第五例此类病例。
