Introduction:
The trichilemmal cyst, also called pilar cyst, is a dermal epithelial cyst originating from the pilar follicle. It usually occurs in the scalp. Hereditary and ossifying cases are rare.
Case Report:
We report the case of a 61-year-old woman presenting with familial multiple trichilemmal cysts, located in the scalp. The histological examination after surgical exeresis confirmed the diagnosis. The trichilemmal cysts featured intra-cystic ossification. The wide dimension of the lesions dimension imposed an extensive surgical scalp exeresis. Reconstruction was performed with a flap after skin expansion.
Discussion:
The trichilemmal cyst is a benign tumor of skin appendages with a slow outcome. Multiple locations may require an extensive surgical scalp exeresis and lead to a problematic reconstruction. Hereditary cases require familial follow-up to prevent such problems.
