Uterine Perivascular Epithelioid Cell Tumor Diagnostic Differences Between Endometrial Curettage Material and Resection Material and Histopathological and Immunohistochemical Approach to the Difficulties in Differential Diagnosis

Uterine perivascular epithelioid cell tumor is a rare mesenchymal tumor consisting of histologically and immunohistochemically distinctive perivascular epithelioid cells. These tumors’ being rare, having different morphological features and having similar immunohistochemical expression findings to that of some tumors lead to diagnostic difficulties and misdiagnoses. In the present case report, we aimed to discuss the traps we fell into while diagnosing the curettage material as neuroendocrine tumor and how we have been directed to the diagnosis of perivascular epithelioid cell tumor, as well as to discuss what to be taken into account while making the differential diagnosis under the guidance of the literature.
