Abstract
A 74-tear-old man presented to our hospital with a 2-year history of a painless and slow-growing fixed mass in the left paratesticular region. There were no specific abnormalities in the laboratory data, and the tumor markers were within normal limits. Computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US) revealed findings suggestive of either inguinal hernia or lipoma. However, intraoperatively, the tumor was observed to roll up the isolateral spermatic cord and testicular vessels, which led to the differential diagnosis of liposarcoma. The tumor was then widely resected along with the left testis, spermatic cord, and testicular vessels. Histopathologic study confirmed the diagnosis of well-differentiated liposarcoma, but no malignant cells were found in any of the surgical margins. A periodical follow-up has been performed by US every 3 months, and no evidence of recurrence or metastasis has been seen in the 6 months since his operation, without any postoperative adjuvant therapy.
