Abstract

|
Trichilemmal carcinoma is a rare malignant neoplasm of the hair follicle from the outer root of the hair follicle sheath. This tumor can be misleading, and a false diagnosis of a squamous cell carcinoma. We report a case of trichilemmal carcinoma with a review of literature. The patient presented with an exophytic well circumscribed nodular mass on the left auricle, which was detected 6 months ago. Histopathologically, the tumor consisted of atypical clear cells which contained abundant glycogen. The tumor cells shows lobular growth pattern with necrosis, foci of trichilemmal keratinization and peripheral pallisading. Total excision and repair with full-thickness skin graft was done with minimal surgical morbidity. The patient has been free of recurrence or metastasis for 8 months.
