Perivascular epithelioid cell tumor (PEComa) is an extremely rare mesenchymal tumor, which ...
PEComas are uncommon mesenchymal tumors often involving the pelvic organs. They have an unpredictable behavior. Accurate diagnosis and long-term follow-up is therefore essential in these patients. We report this case of PEComa of uncertain malignant potential in an unusual location with excellent prognosis.
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...
Lymphangioleiomyomatosis (LAM) is a rare, proliferative lung disease, leading to progressive damage of their structure and member the PEComa neoplasm family (perivascular epithelioid cell tumors). In patients, solid-cystic masses described as lymphangioleiomyoma or extrapulmonary LAM (E-LAM) can occur. E-LAM foci have been in mediastinum, supraclavicular lymph nodes, liver, walls small large in...
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...
