目的:探讨胰腺浆液性微囊性腺瘤( serous microcystic adenoma of pancreas, SMAP)临床病理学特征及鉴别诊断。方法采用免疫组化EnVision两步法对11例SMAP进行检测,回顾性分析其临床病理学特征,并复习相关文献。结果11例SMAP患者均为女性,发病年龄41~68岁,平均55岁,伴右上腹疼痛、恶心、呕吐、消瘦等临床症状。肿物位于胰腺头部5例(45.5%)。11例SMAP中10例为单发,1例为多发,肿瘤界清,切面呈蜂窝状。镜下见肿瘤由大小不一的小囊构成,囊壁内衬单层扁平或立方上皮细胞,胞质透亮,细胞核小、无异型。免疫表型:11例SMAP均表达CK、CK7、CK18、CK19、EMA,3例表达NSE、α-ACT,CgA、Syn、vimentin、TG、Calretinin均阴性,Ki-67增殖指数﹤1%,D2-40、CD34血管阳性,二者在肿瘤细胞中阴性。结论 SMAP是一种少见的胰腺良性肿瘤,需与胰腺寡囊型囊腺瘤、假性囊肿、黏液性囊腺瘤、淋巴管瘤和毛细血管瘤、间皮瘤鉴别。
目的:探討胰腺漿液性微囊性腺瘤( serous microcystic adenoma of pancreas, SMAP)臨床病理學特徵及鑒彆診斷。方法採用免疫組化EnVision兩步法對11例SMAP進行檢測,迴顧性分析其臨床病理學特徵,併複習相關文獻。結果11例SMAP患者均為女性,髮病年齡41~68歲,平均55歲,伴右上腹疼痛、噁心、嘔吐、消瘦等臨床癥狀。腫物位于胰腺頭部5例(45.5%)。11例SMAP中10例為單髮,1例為多髮,腫瘤界清,切麵呈蜂窩狀。鏡下見腫瘤由大小不一的小囊構成,囊壁內襯單層扁平或立方上皮細胞,胞質透亮,細胞覈小、無異型。免疫錶型:11例SMAP均錶達CK、CK7、CK18、CK19、EMA,3例錶達NSE、α-ACT,CgA、Syn、vimentin、TG、Calretinin均陰性,Ki-67增殖指數﹤1%,D2-40、CD34血管暘性,二者在腫瘤細胞中陰性。結論 SMAP是一種少見的胰腺良性腫瘤,需與胰腺寡囊型囊腺瘤、假性囊腫、黏液性囊腺瘤、淋巴管瘤和毛細血管瘤、間皮瘤鑒彆。

Purpose To study the clinicopathologic features and differential diagnosis of serous microcystic adenoma of pancreas ( SMAP) . Methods Immunohistochemical study was carried out, and the clinical and pathologic features were evaluated in 11 cases of SMAP, and review the literatures. Results The age of onset of 11 cases of SMAP ranged from 41~68 years ( average=55 years) . All of them were females. The clinical presentations were right upper abdominal pain, nausea, vomiting and weight loss. Five tumors located in the pancreas head (45. 5%). Grossly, ten cases were solitary, one case was multiple. The boundary of tumor was clear, the cut surface of tumor was honeycomb. Histologic examination showed that the tumors were made up of small sized capsule wall lining of single-layer flat or cube epithelial cell. The cytoplasm was clear, nucleus was small and no atypical features. Immunohistochemical study showed that all of the 11 cases were positive for CK, CK7, CK18, CK19, EMA, 3 cases were positive for NSE,α-ACT, all of the 11 cases were negative for CgA, Syn, vimentin, TG, Calretinin. Ki-67<1%. Vascular vessels were positive for D2-40 and CD34. Conclusions SMAP is a very rare benign tumor of pancreas. It should be distinguished from oligo-cystic cystadenoma, pseudocyst, mucinous cystadenoma, lymphangioma and capillary hemangioma, mesothelioma.
