摘要
Abstract
Objective: To determine the clinicopathological features of perivascular epithelioid cell neoplasm (PEComa) in the retroperitoneum, and to improve awareness and diagnostic level of the tumor. Methods: A case of PEComas in the retroperitoneum was studied by dinicopathologic analysis and immunohistochemistry, with review of the relevant literatures. Results: Histologically, the tumor was composed mainly of prominent epithelioid cells, with abundant eosinophilie pale granular cytoplasms. The stroma was rich in blood vessels. Immunohistochemically, the tumor cells were positive for HMB45, melan A, smooth muscle actin, and Desmin, partially positive for epithelial membrane antigen and vimentin, but negative for CgA, Syn, S-100, CD117, CD34, cytokeratin, calretinin, and inhibin. Conclusion: The PEComa is a rare tumor in the retroperitoneum, with unique morphological and immunohistochemical characteristics. The differential diagnosis of PEComa from other epithelioid cell tumors in retroperitoneum should be considered.关键词
