鼻神经内分泌癌的临床病理学观察

Nasal neuroendocrine carcinoma: a clinicopathological analysis

目的 分析鼻神经内分泌癌的临床病理特点、诊断和鉴别诊断。方法 用形态学和免疫组化等方法观察 1 2例鼻神经内分泌癌的病理学变化。结果 1 2例鼻神经内分泌癌多为中青年 ,男女之比为 5∶1 ,平均年龄 39 6岁。神经内分泌癌的分型 :小细胞型 8例 ,大细胞型 3例 ,不典型型 1例。8例在透射电镜下见癌细胞胞浆内有大小不等的神经内分泌颗粒。肿瘤细胞对EMA、CK、CgA、NSE及Syn均呈阳性。

Objective To analys the clinicopathological features and pathological diagnosis and differential diagnosis of the nasal neuroendocrine carcinomas (NEC). Methods 12 cases of nasal neuroendo crine carcinomas were studied with clinical datas and light microscopic examination and electron microscopic and immunohistchemical staining. Results The majority of the patients were middleaged. The patient population was composed of 10 meles and 2 females(sex ratio,5:1) with average age 39 6 years. On pathological examination,8 of them were small cell type neuroendocrine carcinoma,3 large cell type neuroendocrine carcinoma and 1 atypical ueuroendocrine carcinoma. Electron microscopy of 8 cases showed abundant neuroendocrine granules in the tumors. Immunohistochemical analysis showed that cells expressed EMA,CK,CgA,NSE and Syn Conclusions The key point for clinicopathological features of the NEC were discussed. Its differentila diagnosis includes malignant lymphoma, undifferentiatel carcinoma, malignant melanoma and olfactory neuroblastoma. Histological type of the tumor is important for clinical treatment plan and prognostic evaluation
