A case of an unusual oncocytic variant of minor salivary gland adenocarcinoma presenting in the base of the tongue in a 79 year old male with a remote history of regional radiotherapy is presented. The tumor had a striking morphologic similarity to the more common granular cell tumor, with which it could have been easily confused, leading to significant misdiagnosis. The light microscopic, cytologic, immunohistochemical and electron microscopic features are presented, with a discussion of the differentiating features of this lesion compared to other more common benign and malignant glossal tumors.
本文报告了一例罕见的小涎腺腺癌嗜酸细胞变体病例，该病例发生于一名79岁男性的舌根，患者有区域放疗史。该肿瘤在形态学上与更常见的颗粒细胞瘤有显著相似性，很容易与之混淆，从而导致严重误诊。文中呈现了该肿瘤的光镜、细胞学、免疫组化和电镜特征，并讨论了该病变与其他更常见的良性和恶性舌部肿瘤的鉴别特征。
