Perivascular epithelioid cell tumour (PEComa) of the inferior vena cava presenting as an adrenal mass
A 54-year-old woman had a mass located in the right suprarenal area. On imaging, this mass appeared to be infiltrating the inferior vena cava (IVC). Exploratory laparotomy was undertaken and excision of the tumour was done with the sleeve of the involved IVC. The mass turned out to be a perivascular epithelioid cell tumour (PEComa) on histopathological examination. This report describes previou...
متن کاملPerivascular epithelioid cell tumor (PEComa) in the genitourinary tract.
Perivascular epithelioid cell tumors (PEComas) are mesenchymal tumors composed of histologically, immunohistochemically, ultrastructurally, and genetically distinctive cells. PEComas have been described in different organs and are considered ubiquitous tumors. In this review we discuss recent informations related to PEComas in the genitourinary tract.
متن کاملPigmented perivascular epithelioid cell tumor (PEComa) arising from kidney
INTRODUCTION Perivascular epithelioid cell tumor (PEComa) is a mesenchymal neoplasm composed of perivascular epithelioid cells with clear to eosinophilic cytoplasm. 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 کاملPerivascular epithelioid cell tumor (PEComa) of the liver diagnosed by contrast-enhanced ultrasonography.
Perivascular epithelioid cell (PEC) is a unique cell which expresses both myogenic and melanocytic markers, and forms PEComa. A 36-year-old woman presented with a 35 mm-diameter liver tumor. MRI showed poor fat component in the tumor. Contrast-enhanced ultrasonography using the newly developed enhancing reagent, Sonazoid, clearly demonstrated early-phase enhancement of the tumor and rapid drain...
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 ...
