目的：探讨垂体细胞瘤的临床病理学特征。方法回顾性分析10例垂体细胞瘤的临床病理资料，并复习相关文献。结果10例患者中男性4例，女性6例，年龄4~68岁。肿瘤由伸长的双极梭形细胞构成，肿瘤细胞表达S-100（10/10）、vimentin （10/10）、GFAP（10/10）、EMA（4/10），不表达CKpan，Ki-67增殖指数1%~5%。随访9例患者，均存活，其中1例女性患者术后2年复发。结论垂体细胞瘤是一种低级别、好发于鞍区的梭形细胞肿瘤，成人多见，肿瘤易与毛细胞星形细胞瘤、神经垂体颗粒细胞瘤等混淆，免疫组化标记有助于鉴别诊断。手术完整切除预后良好，不完全切除者有复发可能。

Purpose To study the c1inica1 and patho1ogica1 features of pituicytoma. Methods Ten cases of pituicytoma were re-trieved. Their c1inicopatho1ogic and immunohistochemica1 features were studied,and the re1ated 1iterature was a1so reviewed. Results The 10 patients aged from 4 to 68 years,with 4 ma1es,and 6 fema1es. The fo11ow-up information of 9 cases was co11ected:a11 of them were survived,whi1e one fema1e recurred 2 years after operation. Histo1ogica11y,the tumor was composed of bipo1ar e1ongated spind1e ce11. Immunohistochemica11y,the tumor ce11s showed strong1y positive for S-100(10/10)and vimentin(10/10),whi1e weak or foca1 positive for GFAP(10/10)and EMA(4/10). CKpan was negative in a11 cases and Ki-67 pro1iferation index was 1ow(1% ~5%). Conclusion Pituicytoma is a 1ow-grade spind1e ce11 tumor,typica11y occurs in the se11ar region. It is most common1y found in adu1ts,especia11y in ado1escent patients. The tumor shou1d be distinguished from pi1ocytic astrocytoma and neurohypophysea1granu1ar ce11 tumor. Pituicytoma exhibits strong1y positive for S-100 and vimentin. Genera11y,this tumor behaves indo1ent1y,but some may re-cur.
