Abstract
A 51-year-old woman was admitted to our hospital for detailed examination and medical treatment of a left inguinal bulge. On palpation, a 4cm in diameter, elastic soft and movable mass was felt in the left inguinal region. Abdominal computed tomography showed a heterogenous, sharply demarcated iso-dense area. Although a definite diagnosis could not be made preoperatively, we performed surgery. Intraoperative findings revealed a hematoma-like tumor in the left inguinal canal. The tumor adhered to the left round ligament of the uterus. The resected specimen had a smooth surface. The tumor was grayish-white and solid. Immunohistochemical staining was positive for HMB-45 and actin. A diagnosis of perivascular epithelioid cell tumor was confirmed. The patient's postoperative course was uneventful. She was discharged on the 2nd postoperative day. Ten months after the operation, to date no recurrence has been observed. We present this case with a review of the literature.
