摘要

多形性低惡性度腺癌是一種小唾液腺的腫瘤，有細胞形狀一致性、組織型態具變異性、生長緩慢、低惡性度又低轉移傾向的特點。好發於口腔內的上腭及頰黏膜，通常硬、軟腭交界處為最常見的起源位置。本例患者為56歲女性，主訴口腔內腫塊已有6年的時間，理學檢查可見一個無痛性、可移動、無易碰觸性出血的紅灰色、表面不規則懸雍垂腫堆，無頸部腫堆。經口腔腫瘤切除手術後，病理切片証實為多形性低惡性度腺癌。術後觀察追蹤至今1年並無復發或是遠處轉移的現象。

Polymorphous low-grade adenocarcinoma (PLGA) is a predominantly minor salivary gland carcinoma, characterized by cytological uniformity, histological diversity, slow growth, low-grade malignancy and a low metastatic potential. PLGA most commonly originates from minor salivary gland tissue of the intra-oral palate and buccal mucosa, and the junction of the hard and soft palate is the commonest site of origin. Described herein is the case of a 56-year-old female who presented with an approximately six year history of an intra-oral mass. ENT examination identified a 3 × 3 cm, non-tender, mobile, reluctantly touch bleeding, reddish to grayish, irregularly textured tumor mass over the uvula. After wide excision via an intra-oral approach, tissue pathology indentified a polymorphous low-grade adenocarcinoma. There have been no signs of recurrence at one year follow up after treatment.
