Summary:We report a typical case of pilomatricoma in the right parotid region. The patient, an 18-year-old man, visited our hospital with a complaint of palpable and painless mass on the right side for two years. Clinical examination revealed a firm nodule that measured 2.0×1.5 cm. The skin was free of unusual pigmentation. CT scans demonstrated a well-demarcated and calcified mass in the subcutaneous tissue. Both clinical features and CT suggested pilomatricoma. Under local anesthesia, we removed the tumor together with a connective tissue capsule. Serum SCC antigen was elevated to 1.9 ng/ml on preoperative examination, but decreased to within the normal range (0.9 ng/ml) 1 month after surgery. Histological examination showed many islands of shadow cells including calcium deposits, and the specimen was diagnosed histologically as pilomatricoma.
