腮腺基底細胞腺瘤-病例報告

Basal Cell Adenoma of the Parotid Gland-Case Report

摘要


基底細胞腺瘤(basal cell adenoma) 為一種罕見之唾液腺良性腫瘤,根據1991年世界衛生組織(World health Organization)的統計,約佔唾液腺腫瘤的1-2%。本例為-63歲男性病人,主訴近6年來,在左耳前下方出現一緩慢增大腫塊,經手術切除後證實為一腮腺基底細胞腺瘤,追蹤2年迄今無復發現象。腮腺是基底細胞腺瘤最常好發的位置,且常見囊性變化,此病例則是呈現由囊壁長出突出至囊腔的結節,組織學上頗為罕見。基底細胞腺很重要的特徵為細胞群的周邊可見上皮細胞的的細胞核呈柵狀排列(palisading),而依其細胞組織結構的不同,可分為實心狀(solid)、小樑狀(trabecular)、管狀(tubular)和膜狀(membranous)等4種。本病例除了膜狀結構外,其餘3種結構皆很明顯。本文亦針對基底細胞瘤之分類式組織學分型加以討論。

Basal cell adenomas are rarely seen in the salivary gland, for only 1% to 2% of all salivary gland tumors, and the parotid gland is the most common location for basal cell adenomas, with encapsulation usually evident. A 63-year-old man who had a slowly growing mass in the left infra-auricular area for six years is presented. After surgical removal, tissue pathology identified a parotid basal cell adenoma. No evidence of recurrence was found over a two-year follow-up period. In the presented case, a nodule arose in a cyst wall and protruded into the cyst cavity, which is a somewhat rare phenomenon. Tumor cell arrangements are categorized as either solid, trabecular, tubular or membranous. Three of these types were identified in this case, with only the membranous type not found. The categories and histological types of basal adenomas are discussed in detail.
