目的:探讨咽旁间隙肌上皮癌的影像学及临床病理特征。方法:分析我院收治的1例咽旁间隙肌上皮癌患者的影像学及临床病理资料,结合文献探讨头颈部肌上皮癌的临床特征。结果:影像学显示咽旁间隙占位性病变;病理学确诊为肌上皮癌,病理免疫组织化学表现为S-100蛋白、平滑肌动蛋白、细胞角蛋白、波形蛋白免疫组织化学阳性染色。临床表现为耳痛、流脓血伴头痛及脑神经损害。结论:肌上皮癌是罕见的预后极差的恶性上皮性肿瘤,好发于颌面部涎腺;发生于咽旁间隙并侵犯颞骨则表现为耳深部疼痛及头痛。影像学表现恶性肿瘤行为,破坏性强。病理免疫组织化学明确诊断。
Objective: To investigate the imaging and clinicopathological features of parapharyngeal space myoepithelial carcinoma. Methods: One case of parapharyngeal interstitial myoepithelial carcinoma treated by our hospital was analyzed with the imaging and clinicopathological data, and the clinical features of head and neck myoepithelial carcinoma were analyzed. Results: Imaging showed space-occupying lesions of parapharyngeal space. Pathological diagnosis of myoepithelial neoplasia was pathological immunohistochemical staining of S-100 protein, smooth actin, cytokeratin and vimentin. Clinical manifestations of earache, pus with fluid and headache and cranial nerve damage. Conclusion: Myoepithelial carcinoma is a rare malignant epithelial tumor with poor prognosis. It occurs in the salivary gland of the maxillofacial region. It occurs in the parapharyngeal space and invades the temporal bone, which is characterized by deep ear pain and headache. Imaging performance of malignant tumors, destructive. Pathological immunohistochemical diagnosis.
