摘要

肌上皮癌（惡性肌上皮瘤）是一種罕見的腫瘤，其定義為惡性唾液腺腫瘤合併所有癌細胞幾乎皆具有肌上皮分化。它可以出現在不尋常的位置，例如鼻咽，而這使得它們可能很難被探究。鼻咽肌上皮癌有時可表現為鼻咽部的腫塊病灶，因而可能被誤認為原發性鼻咽癌。鼻咽肌上皮癌的治療不同於鼻咽癌，儘可能地手術切除主要病變仍被認為是主要的治療方式。這裡，我們提出一個32歲的男性罕見個案，有鼻咽腫塊，起初，被臆斷為鼻咽癌；然而，在病理切片的審查複閱後，鼻咽肌上皮癌的診斷才被確立。

Myoepithelial carcinoma (malignant myoepithelioma) (MC) is a rare tumor, defined as a malignant salivary neoplasm composed almost exclusively of tumor cells with myoepithelial differentiation. It can arise in unusual location sites, such as the nasopharynx, and may be difficult to approach. Nasopharyngeal MC can sometimes present as a nasopharyngeal mass which may be mistaken for primary nasopharyngeal carcinoma (NPC). The treatment strategy for nasopharyngeal MC is different from NPC, and maximal surgical resection of the main lesion is still considered as the mainstay of therapy. Herein we present a 32-year-old man with a nasopharyngeal mass which was initially mistaken as NPC, and which was later confirmed as MC after a comprehensive review of the pathology.
