Malignant perivascular epithelioid cell tumor (PEComa) of the femur: a case report and literature review
BACKGROUND We describe a case of malignant perivascular epithelial cell tumor (PEComa) arising primarily in the distal left femur of a 47-year-old male. CASE PRESENTATION The patient presented with pain accompanied by progressive swelling of his left thigh. Computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed an osteolytic lesion. Curettage of the lesion was reported as...
متن کاملPrimary Perivascular Epithelioid Cell Tumor (PEComa) of the Liver - A Case Report and Review of the Literature -
Perivascular epithelioid cells (PECs) were initially proposed, by Bonetti et al. in 1992, to describe an “unusual atypical cell type” of epithelioid shape and harboring a clear to eosinophilic cytoplasm with perivascular distribution in both renal angiomyolipoma (AML) and clear cell sugar tumor (CCST) of the lung. This perception gradually became accepted and led to the concept of perivascular ...
متن کاملPrimary perivascular epithelioid cell tumor of the liver: new case report and literature review
UNLABELLED Perivascular epithelioid cell tumors (PEComas) encompass a group of rare mesenchymal neoplasms, which typically have a perivascular location with dual melanocytic and muscular differentiation. They are found in a variety of localizations, though lesions in the liver are exceedingly rare. Because of their rarity, the clinical, radiological and histological features of these tumors hav...
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 کاملPigmented Perivascular Epithelioid Cell Tumor (PEComa) of the Kidney: A Case Report and Review of the Literature
Heavily pigmented perivascular epithelioid cell tumors (PEComa) are rare, only eight cases of which have been reported. Unlike typical epithelioid angiomyolipoma, most of these tumors have been encountered in female patients without tuberous sclerosis. The long-term prognosis thereof is undetermined. Cytological similarity and heavy melanin pigment make it difficult for pigmented PEComa to be d...
