肌上皮癌的研究进展

肌上皮癌（myoepithelial carcinoma，MC）是一种罕见的恶性肿瘤，发病部位以涎腺居多，随着免疫组织化学及病理学检查技术不断进步，国内外文献报道临床个案逐渐增多，除最常见的涎腺MC外，有关其他更为少见部位的MC个案病例报道越来越多。本文通过总结目前国内外相关文献报道的个案及研究，结合本院实际经验，综述MC的研究进展，内容包括病因、病理、临床特征、诊治进展以及各种少见部位的MC特征等，旨在为临床MC的诊治提供参考。 

Research progress on myoepithelial carcinoma

Myoepithelial carcinoma is a rare malignant tumor. The primary site of this tumor is the salivary glands. With the rapid ad-vancement in immunohistochemical examination and pathological examination, the number of clinical cases of the most common type of myoepithelial carcinoma of the salivary glands, as well as rare primary sites of myoepithelial carcinoma, reported in the litera-ture has increased. Based on related cases reported in the literature, various studies worldwide, and our personal practical experience, this article summarized advancements in the research on myoepithelial carcinoma, including etiology, pathology, clinical characteris-tics, diagnosis, and treatments, as well as myoepithelial carcinoma features of various rare primary sites. This article aims to provide useful evidence for oncologists in diagnosing and treating myoepithelial carcinoma.
