title: Pilomatrixoma: late onset in two periocular cases.
abstract: First described by Malherbe and Chenantais in 1880, pilomatrixoma is a benign skin neoplasm that arises from hair follicle matrix cells. Clinically, it manifests as a firm, solitary, slow growing, painless nodule of the dermis, more frequently located in the head, neck, and upper extremities. It is typically a tumor of younger individuals and rarely presents in older patients. We report 2 cases of pilomatrixoma, one presenting in a young adult and the other in an elderly patient. Clinical and histopathologic features of the 2 cases are discussed.
