Femoral <scp>PEComa</scp> Treated With Combined Surgery and Radiotherapy: A Case Report

Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal tumor, and primary involvement of the bone is exceptionally uncommon. In this report, a case of malignant PEComa arising from the femur in an elderly patient is described. The patient achieved a favorable therapeutic outcome following surgical resection and adjuvant radiotherapy. This case suggests that this treatment mode may represent a feasible option for elderly patients and provides a valuable reference for clinical management of this rare tumor type.
