Pilomatrixoma in the cheek: a clinical case report

Abstract

Pilomatrixoma is a follicular benign tumor of unknown etiology that originates in the matrix of a hair follicle. It develops more frequently in children and young adults, with a slight predominance in female patients. It is a slow-growing tumor that presents as a mobile nodule, firm, and with well-defined borders. The present study aimed to report the clinical, histopathologic, and radiographic aspects of pilomatrixoma in the cheek area of a 20-year-old female patient as the established treatment at an oral maxillofacial department. Pilomatrixoma is rarely included in the differential diagnosis of masses and nodules in the skin, and it is often confused with other nodular lesions, such as epidermoid cysts. The diagnostic method to identify this entity is an incisional biopsy. Because of its high incidence in the head and neck region, oral surgeons should be well-acquainted with this type of tumor so that it can be included as a diagnostic hypothesis of masses and nodules of the head and neck.

Demographic and clinicopathological features and long-term results of pediatric cases diagnosed with pilomatrixoma

“…[5] Gardner syndrome, myotonic dystrophy, Steinert's disease, and pilomatrixoma with sarcoidosis were identified, although no significant correlation was established between these diseases and pilomatrixoma. [9] In our study, while the lesions were mostly found in the head and neck region, multiple nodules were detected in only three cases. There was no other accompanying disease in the history and clinical evaluations of our patients.…”

“…It was reported that 40% of these tumors are seen under the age of 10, and more than 60% are seen in the first two decades of life. [9] About 40% of lesions are seen in the sixth and seventh decades. In our study, 66.2% of the cases were between the ages of 10 and 18.…”
