Malignant perivascular epithelioid cell tumor (PEComa) of cervix with TFE3 gene rearrangement: a case report.
In this study, we reported the first PEComa arising within the cervix with TFE3 gene rearrangement and aggressive biological behavior. Morphologically, the tumor showed infiltrative growth into the surrounding parenchyma. The majority of tumor cells were arrayed in sheets, alveolar structures, or nests separated by delicate fibrovascular septa. There was marked intratumoral hemorrhage, necrosis...
متن کاملPigmented perivascular epithelioid cell tumor (PEComa) arising from kidney

Pigmented PEComa arising from kidney is extraordinarily rare and sometimes can exhibit aggressive biological behavior. CASE REPORT We present here a rare case of pigmented renal PEComa in a 46-year-old female. The patient had comp...

متن کاملHepatic perivascular epithelioid cell tumor (PEComa): a case report with a review of literatures
Hepatic perivascular epithelioid cell tumors (PEComas) are very rare. We report a primary hepatic PEComa with a review of the literature. A 56-year-old women presented with a nodular mass detected during the management of chronic renal failure and chronic hepatitis C. Diagnostic imaging studies suggested a nodular hepatocellular carcinoma in segment 5 of the liver. The patient underwent partial...
متن کاملMalignant Perivascular Epithelioid Cell Neoplasm (PEComa) of the Pelvis: A Case Report
Perivascular epithelioid cell neoplasms (PEComa) are rare mesenchymal tumors that can occur in any part of the body and have unpredictable pathological behavior. They are usually benign, but may be malignant. We present a case of malignant PEComa of the pelvic retroperitoneum treated with radical surgery.
