| Abstract: | Objective]To investigate the clinical and pathological characteristics of the peritoneal or retroperitoneal stromal tumors.Methods]The clinical pathologic data and the expression of CD117、CD34、SMA、S-100 measured with immunohistochemistry in 11 cases with the peritoneal or retroperitoneal stromal tumors in the late 3 years were studied retrospectively.Results]In the 11 cases,3 locate in the district up the colon,8 locate in the district down the colon.The 4 tumors can’t be cut off completely by surgery.The tumor <2cm(n=2), 2~5cm(n=1),5~10cm(n=3),>10cm(n=5).9 cases mainly show spindly cell type,2 mainly show epithelioid cytologyic feature.In 11 cases,all are CD117 positive,7 are CD34 positive, 5 are SMA positive,none is positive in S-100.Conclusion]The results suggest that the peritoneal or retroperitoneal stromal tumor is an especial kind of GIST,but it has its own clinical and pathological characteristics. |
