Abstract
Accurate preoperative diagnosis is highly important for the treatment of perivascular epithelioid cell tumors (PEComas) because PEComas are mainly benign tumors and may not require surgical intervention. By analyzing the causes, properties and clinical manifestations of PEComas, we summarize the challenges and solutions in the diagnosis of PEComas.
Core Tip: Hepatic perivascular epithelioid cell tumors (PEComas) are mesenchymal tumors composed of histologically and immunohistochemically unique perivascular epithelioid cells. They have nonspecific clinical manifestations, inconspicuous and variable imaging features and complex pathological phenotypes, which make preoperative diagnosis very difficult. By enumerating the practical problems faced by clinicians in the diagnosis and treatment of PEComa patients, we analyzed the methods and ideas used to improve the accuracy of preoperative diagnosis of PEComas and provided new insights into the choice of conservative treatment and surgical treatment.
