Abstract:
Trichilemmal carcinoma is a rare malignant neoplasm of the hair follicle, which is derived from or differentiates towards cells of the outer root sheath. We report a case of trichilemmal carcinoma in an 83-year-old female patient. She presented with a tender dome-shaped crusted papule showing a feature of cutaneous horn on the forehead, which was first detected 6 months before. nstopathologically, lobular patterned tumor cells with peripheral palisade of basaloid cells, nuclear atypia, and clear or pale, PAS-positive, diastase-sensitive cytoplasm were observed beneath the marked hyperkeratosis. After the diagnosis, total excision was done. The patient has been free of recurrence or metastasis till now.
