A Case of Trichilemmal Carcinoma

Abstract

We report a case of trichilemmal catcinoma in a 79-year-old woman presentde an atrophic scar remaining after excision of a recurrent nodule on the right mandibular area, Her past history revealed that there had been a painful pea-sized brownish nofule on the same site for two years. Eleven months before presentation, it had been excised but recurred 9 months later. Histopathologic findings showed a clear cell neoplasm with trichilemmal keratinization. The tumor cells showed PAS-positive cytoplasm and cytologic atypia with a few mitoitic figures. Immunohistochemical staining for high molecular weight cytokeratin was positive but carcinoembryonic antigens and epithelial membrane antigens were all negative. To our knowledge this is the first report of trichilemmal carcinoma in Korea.
