摘要


毛囊上皮瘤為良性腫瘤,可為單發或多發性。多發性毛囊上皮瘤為遺傳顯性,通常自青少年期出現,好發於顏面中央,呈對稱性分佈。呈線狀及神經節分佈之多發性毛囊上皮瘤極為罕見,目前文獻上只有兩例報告。本篇報告一在左側鼻樑的線性毛囊上皮瘤病例,其分佈位於三叉神經第一支之鼻睫分支。症灶在經過四次二氧化碳雷射治療後獲得明顯的改善,追蹤四年未有復發的情形。

Trichoepitheliomas are benign neoplasms and can occur as either solitary or multiple lesions. Multiple lesions are inherited as an autosomal dominant trait. They usually appear at puberty and are distributed symmetrically over the central area of the face. Only two cases of multiple trichoepitheliomas presenting as a linear streak and in a dermatomal distribution have been reported . We describe a new case of multiple trichoepitheliomas with a linear distribution over the nasal bridge and left nasal sidewall. The distribution corresponds to the dermatomal area of the trigeminal nerve (V1 division, nasociliary branch).Dramatic clinical improvement followed carbon-dioxide laser treatment. There has been no evidence of recurrence over four years of follow-up.
