Abstract

Trichoblastoma is a benign cutaneous neoplasm that consists of follicular germinative cells. There have only been a few case reports describing the malignant counterpart of trichoblastoma. We report trichoblastic neoplasms that show histological features of malignancy. The histological sections revealed locally aggressive neoplasms showing prominent differentiation towards hair germ and follicular sheath with formation of papillary mesenchymal bodies and follicular bulb-like structures. The tumor was widely excised with a clear margin. No sign of recurrence has been noted 1 year later.
