Pilomatricoma is a benign skin appendage tumor derived from the outer sheath cell of hair follicle, most commonly seen in children and adolescents. It is usually found on head, neck and upper extremities as a painless superficial skin mass. We report a 12-year-old boy presenting with a painless, slow-growing mass in right posterior neck for 4 months. The physical examination revealed a movable solitary firm nodule. The computed tomography scan revealed a well-demarcated and non-homogenous calcified mass with estimated size of 1.5 × 0.8 cm. The tumor was totally removed under general anesthesia, and the histopathology reported a pilomatricoma. There was no evidence of recurrence after 6 months of follow-up.
