Abstract

|
|
|
The pilomatricoma is a benign skin neoplasm arising from hair follicle matrix cells, and it comprises approximately 0.12% of all benign skin tumors. It occurs most commonly in head and neck. It usually tends to occur in childhood or school-age. Mainly, it exists in single subcutaneous or intradermal nodule and grows very slowly. The diagnosis is confirmed by histopathologic examination. Histopathologically, it is characterized by basaloid cells, enucleated shadow cells and calcifications in the shadow cell. However, it is rare to present extensive ossification in pilomatricoma. The treatment of choice is wide local excision. A 66-year-old man came to our clinic and he complained of two masses on right parotid tail and posterior neck. We performed excisional biopsy on posterior neck and partial parotidectomy. The pathology of former was pilomatricoma with extensive ossification. We report a rare unique case of pilomatricoma with brief review of literature.
