左頰巨大多形性腺瘤－病例報告

根據研究，多形性腺瘤爲最常見的良性腫瘤，主要好發於大唾液腺，多呈現爲多葉型腫瘤，以40~50歲較常見，有女性較多之傾向。文獻報告指出，原發位置在小唾液腺者約佔10%，其中又以腭部、唇部居多，頰部之多形性腺瘤相當罕見。這類病人在發病時多無明顯症狀，主要症狀爲臉部不對稱，此類腫瘤是呈現出無痛感及緩慢生長，因而病人容易忽略病情。組織學上由於多樣的組織分化，又通稱爲混合瘤。回顧文獻，目前主要的治療方式仍爲手術切除腫瘤及其包膜爲主。本篇病例報告提出一巨大罕見的案例，發生於54歲的台灣男性。根據病人自述此腫瘤持續約10年之久，因爲疼痛及異物感加重至本科求診，在電腦斷層下測量約7公分×6.1公分×6.5公分之一巨大腫瘤，位於少見的左頰間隙、左側顳下間隙及左側下教翼狀間隙。由於此病例之多形性腺瘤生長位置罕見，且延伸至顳下間隙區域，我們成功將此巨大腫瘤，經由口內方式做一摘除，術後追蹤至今並無復發，故提出報告。
