Abstract

Epithelial–myoepithelial carcinoma (EMC) is characterized by a biphasic cytomorphology comprising inner duct-forming epithelium and outer, prominently clear, enveloping myoepithelial cells. EMC typically occurs in major salivary glands, but also in the minor glands of the oral mucosa. We report herein a rare case of EMC arising from the intrabuccal mucosa in a 28-year-old man, with no recurrence after surgical excision and postoperative radiotherapy despite of partially positive surgical margin for tumor. The clinical and pathological features of this tumor are discussed.

颊内粘膜小涎腺上皮-肌上皮癌1例
上皮-肌上皮癌(EMC)的特征是双相细胞形态,包括内部导管形成的上皮和外部明显透明的包膜肌上皮细胞。EMC通常发生在大唾液腺,但也发生在口腔黏膜的小腺体。我们在此报告一位28岁的男性患者,发生于颊内粘膜的罕见EMC,尽管手术切缘部分阳性,但手术切除和术后放疗后未复发。本文讨论了该肿瘤的临床和病理特征。
