目的:探讨胃血管球瘤的病理学特点及临床表现。方法:对1例胃血管球瘤进行组织学表现、免疫组化染色观察及文献复习。结果:组织学特点:肿瘤细胞围绕薄壁血管呈实性排列,大小一致,圆形或多角形,胞质丰富红染或透亮,界限清楚。免疫组化特点:肿瘤细胞表达SMA(++)、Vimentin(+++)。结论:胃血管球瘤是胃一种少见的肿瘤,易误诊为胃肠间质瘤、平滑肌瘤及类癌,可以通过免疫组化染色及形态学观察进行鉴别诊断。
Objective: To investigate the pathological features and clinical manifestations of gastric gliomas. Methods: One case of gastric glioma was studied by histological examination, immunohistochemical staining and literature review. Results: Histological features: Tumor cells were arranged around the thin-walled blood vessels with the same size, round or polygonal shape, rich orchids, or bright clear cytoplasm. Immunohistochemical features: tumor cells express SMA (++), Vimentin (+++). Conclusion: Gastric glioma is a rare tumor in the stomach. It is easily misdiagnosed as gastrointestinal stromal tumors, leiomyomata and carcinoid tumors, and can be differentially diagnosed by immunohistochemical staining and morphological observation.
