摘要

毛髮基質瘤（pilomatricoma）是由毛囊的外根鞘（outer root sheath）細胞分化出來的良性皮膚腫瘤，以皮膚突起或隆起來表現。好發部位有頭部、頸部及上肢。本文報告1名12歲女性，因半年來逐漸長大之右後頸部無痛腫塊求診，電腦斷層檢查顯示為0.9 × 1.3 × 2 cm界線明顯之非均質鈣化病灶。經手術切除証實為毛髮基質瘤，術後追蹤6個月無復發現象。在此提出病例報告，供讀者參考。

Pilomatricoma is a benign epithelial tumor differentiated from the outer root sheath cell of hair follicle. It usually presents with a painless skin lump. In most cases, the tumor occurs in the head, neck, and upper limbs. In this report, a 12-year-old girl presented to our clinic with a painless, slow-growing mass in right posterior neck for half a year. The physical findings were essentially normal except a non-tender mass of estimated size of 2 × 2 × 1 cm was palpated in right posterior neck. The computed tomography scan revealed a well-demarcated and non-homogenous calcified mass in right posterior neck, and the size of the mass was measured 2.0 × 1.3 × 0.9 cm. An operation was performed under general anesthesia, and a well encapsulated, firm, and calcified tumor was identified just underneath the skin flap. The tumor was removed en bloc and the histopathology reported a pilomatricoma of the neck. There was no evidence of recurrence in the post-operative 6 months.
