目的分析小肠血管瘤的临床及病理组织学特征。方法运用光镜及免疫组化技术观察6例小肠血管瘤,同时复习相关文献。结果6例小肠血管瘤中,男性4例,女性2例;平均年龄31岁。消化道出血2例,腹痛2例,腹部包块1例,肠梗阻1例;术前仅有1例拟诊血管瘤,误诊5例;6例手术治疗,均痊愈,其中毛细血管瘤1例,海绵状血管瘤3例,混合型2例。免疫组化示CD34、Ⅷ因子、actin、SMA和Vim(+),CK(-)。结论小肠血管瘤是一种比较少见的小肠良性肿瘤,容易误诊,但若能确诊,手术治疗预后很好。
Objective To analyze the clinical and histopathological features of small intestinal hemangiomas. Methods Six cases of small bowel hemangioma were observed by light microscopy and immunohistochemistry, and the related literatures were reviewed. Results 6 cases of small bowel hemangiomas, 4 males and 2 females; mean age 31 years. 2 cases of gastrointestinal bleeding, abdominal pain in 2 cases, abdominal mass in 1 case, intestinal obstruction in 1 case; only 1 case preoperative diagnosis of hemangioma, misdiagnosis in 5 cases; 6 cases of surgical treatment, were cured, including 1 case of capillary hemangioma , Cavernous hemangioma in 3 cases, mixed type in 2 cases. Immunohistochemistry showed CD34, factor Ⅷ, actin, SMA and Vim (+), CK (-). Conclusions Small intestinal hemangioma is a relatively rare benign tumor of small intestine and is easily misdiagnosed. However, if diagnosed, surgical treatment has a good prognosis.
