Abstract: Aims: Primary peritoneal serous carcinoma (PPSC) is an unusual neoplasm that has not been properly characterized. To better
define the clinicopathological and immunohistochemical features of PPSC, we present 6 such cases. Methods: The 6 patients consisted of
one man and 5 women, ranging in age from 45 and 75 years. None of the patients had any history or clinical evidence of tumor elsewhere. The
immunohistochemical profile was examined using antibodies against β-catenin, E-cadherin, wnt5a, EGFR, VEGF, vimentin, Ki67, and P53.
Results: Of all the 6 PPSC cases, 5 cases presented stage IIIC and 1 case presented stage IV. Microscopically, 5 cases were poorly
differentiated and 1 was moderately differentiated. All cases showed positive staining for β-catenin, E-cadherin, vimentin, VEGF, P53, and Ki67,
4 cases expressed EGFR, and all cases were consistently negative for wnt5a. Conclusions: We described 6 cases of PPSC with
clinicopathological and immunohistochemical features. The findings provide basic knowledge of PPSC. (IJCEP1207009).
