I like your guy's differential diagnosis. This patient had the same tumor 10 years ago and was diagnosed "pleomorphic adenoma" in an outside institution. Now, it appears that it has recurred. I am taking two more photos. Is this time "pleomorphic adenoma" again or something else? （译文：我很欣赏大家的鉴别诊断，患者10年前在外院诊断为多形性腺瘤,现在似乎是复发,我又提供两幅图,,这次它是其它肿瘤还是混合瘤复发?）

考虑 基底细胞腺瘤

 腺上皮粘连较好，见乳头样结构，细胞多层次，异型性小。低倍边缘似栅栏样排列。首先考虑小涎腺基底细胞腺瘤。

 A 62岁女，鼻唇沟包块，经口腔内穿刺涂片，镜下见致密排列的上皮细胞团，细胞温和，如果不说部位先考虑乳腺纤维腺瘤。在这考虑二个，汗腺瘤，多形性腺瘤。
