Pilomatrixoma is a benign neoplasm of ectodermal hair follicle germinal matrix cell origin. At least 50% of pilomatrixomas are reported to arise in the head and neck, and 40% occur before the age of 10 years. 1-3 Pilomatrixoma is the third most common reason for excision of a cervicofacial mass in children, after lymphadenopathy and epidermoid cysts.

Carcinomatous transformation in a pilomatrixoma
The American Journal of Dermatopathology, 1984A case of a pilomatrixoma with exceptional features in an 18-year-old man is described. The lesion presented itself as a mass in a supraclavicular fossa. Four attempts at extirpation by conservative local excisions were failures. It recurred each time but was finally ablated by a radically wide excision and closure by a deltopectoral flap.

Ossifying Pilomatrixoma of the Eyelid
Ophthalmic Plastic & Reconstructive Surgery, 2020Pilomatrixoma, an uncommon, usually benign cutaneous appendageal tumor, shows differentiation toward the hair follicle matrix cell. It undergoes various histopathologic stages, early on displaying epithelial and shadow cells along with granulomatous inflammation.

Pilomatrixoma of the head and neck
Head & Neck Surgery, 1984AbstractPilomatrixoma is an uncommon neoplasm which occurs most frequently in the head and neck region. It usually presents as a slowly growing dermal or subcutaneous mass. Unfamiliarity with this lesion may lead the physician to mistake it for more common infectious or neoplastic processes.

Differentiation and Apoptosis in Pilomatrixoma
The American Journal of Dermatopathology, 2011We carried out a histopathologic study of pilomatrixoma, a benign skin tumor, and also examined apoptosis and hair differentiation with the aim to understand the presence of amorphous debris and cyst formation in the tumor. Among 16 cases of pilomatrixoma examined, 11 were at the early regressive stage and 5 were at the late regressive stage according ...
