Abstract:
Desmoplastic trichilemmoma is a rare variant of trichilemmoma characterized by typical features of trichilemmoma with abundant desmoplastic stroma. We report herein a 54-year-old man presented with 2-year history of a solitary bean sized verrucous nodule on the occipital scalp. Histologically, the tumor showed a well-defined lobular growth extending from the epidermis into the dermis with abundant central desmoplastic stroma. Epithelial lobules at the margins of the neoplasm showed the typical features of trichilemmoma composed of glycogen-rich clear cells and peripheral palisading columnar cells. In contrast, at the center the cells assume a more random pattern of cords and strands traversed by the hyaline stroma, mimicking invasive carcinoma. It was diagnosed desmoplastic trichilemmoma by the distinctive histologic appearance and totally excised.
