Perivascular epithelioid cell tumor of the lung, also known as clear cell "sugar" tumor, is a rare benign tumor arising from perivascular epithelioid cells. Herein, we present a case of spindle cell subtype of pulmonary perivascular epithelioid cell tumor with prominent calcification and malignant potential in a 49-year-old woman. Histologically, the striking feature of this lesion was attribut...
BACKGROUND Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal tumor composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. The perivascular epithelioid cell (PEC) co-expresses melanocytic and muscle markers. Since no normal counterpart to the PEC has ever been identified in any normal tissue, the cell origin of these tumors is still unce...
Uterine perivascular epithelioid cell tumor is a rare mesenchymal consisting of histologically and immunohistochemically distinctive cells. These tumors’ being rare, having different morphological features similar immunohistochemical expression findings to that some tumors lead diagnostic difficulties misdiagnoses. In the present case report, we aimed discuss traps fell into while diagnosing cu...
PEComa of the uterus with coexistence of situs inversus totalis, a case report and literature review
PEComas are a group of very rare mesenchymal neoplasms, which express myogenic and melanocytic markers, such as HMB-45 and actin. Situs inversus totalis represents a complete left to right side transposition of the asymmetrical thoracic and abdominal organs and incorporates dextrocardia. The presence of uterus PEComa in the setting of situs inversus totalis is extremely rare. Here, we report a ...
