Trichoepithelioma - DermNet
Trichoepithelioma is caused by the benign proliferation of epithelial -mesenchymal cells (basal cells) of hair follicles. There are three variants: solitary, multiple, and desmoplastic. Solitary nodules are the least common and usually spare the eyelids.

Trichoepithelioma pathology - DermNet
Classified as one of the tumours of the follicular epithelium, trichoepithelioma is thought to arise from the hair germ. Scanning power view reveals a tumour comprised of multiple nodules situated within the dermis (Figure 1). Small horn cysts, abortive hair follicles and calcification are frequently seen (Figure 2).
Trichoepithelioma: Causes, Symptoms and Treatment
Trichoepithelioma is a rare skin condition characterized by the development of small, firm nodules on the skin, primarily on the face. These nodules are benign tumors that arise from the hair follicles, typically presenting as single or multiple lesions.
Trichoepithelioma - EyeWiki
Trichoepithelioma is a rare benign adnexal neoplasm originating from basal cells of hair follicles. They may appear as solitary or multiple nodules most commonly on the face, though solitary lesion isolation to the eyelid is exceedingly rare [2] [3] [4].
Desmoplastic trichoepithelioma - DermNet
What is a desmoplastic trichoepithelioma? Desmoplastic trichoepithelioma is a harmless facial skin lesion. It is an uncommon form of trichoepithelioma, with a reported incidence of 1 in 5000 skin biopsies in a cohort of British adults. It has also been called ‘sclerosing epithelial hamartoma’.
