“Malignant” Perivascular Epithelioid Cell Neoplasm: Risk Stratification and Treatment Strategies
Purpose. Perivascular epithelioid cell tumors (PEComas) are a rare collection of tumors characterized by a myomelanocytic phenotype, and PEComas occurring in "nonclassic" anatomic distributions are known as perivascular epithelioid cell tumor not otherwise specified (PEComa-NOS). This review aims to compile and analyze cases of PEComa-NOS in an effort to better define their natural history. Des...
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.
متن کاملMalignant Perivascular Epithelioid Cell Neoplasm of the Mediastinum and the Lung
A perivascular epithelioid cell neoplasm (PEComa) in the chest is rare, let alone in the mediastinum and lung. A 63-year-old man was admitted to our hospital with chest pain for more than 2 months and was found to have an opacity in his mediastinum and lung for 3 weeks. Enhanced chest computed tomography (CT) revealed a mass in both the left upper lobe and central anterior mediastinum. To ident...
متن کاملMalignant TFE3-rearranged perivascular epithelioid cell neoplasm (PEComa) presenting as a subcutaneous mass.
Perivascular epithelioid cell neoplasms (PEComas) are a group of mesenchymal tumours with concurrent melanocytic and myogenic differentiation. Although many cases are sporadic, PEComas can be associated with tuberous sclerosis. A distinct subset of deep-seated PEComas has been shown to carry TFE3 fusions. To our knowledge, this is the first reported case of primary subcutaneous malignant PEComa...
متن کاملMalignant perivascular epithelioid cell tumor of the uterus
Perivascular epithelioid cell tumors (PEComas) are a rare collection of tumors arising in a wide array of anatomic locations and characterized by a myomelanocytic phenotype. PEComas which occur in non-classic anatomic distributions are known as perivascular epithelioid cell tumor-not otherwise specified (PEComa-NOS), and one of the most common primary sites for PEComa-NOS is the uterus. The ris...
