Retroperitoneal liposarcoma presenting a indirect inguinal hernia

A 60-year-old man was admitted to our hospital with a right inguinal swelli ng that had been growing in size without any pain for 7 months. We diagnose d the growth as a right inguinal hernia and operated on him. The growth, ho wever, was found to be a tumor it situated along the spermatic cord and tes ticular vessels. We diagnosed it as a lipoma, The tumor was resected near p art of the internal inguinal ring. Histopathological diagnosis showed well- differentiated liposarcoma of the sclerosing type. Postoperative computed t omography (CT)I revealed a large residual tumor in the retroperitoneum, We believed that the tumor was a retroperitoneal liposarcoma and that it devel oped in the inguinal region. The residue of the liposarcoma was resected on to the right inguinal tract. A periodic follow up has been performed and no evidence of recurrence or metastasis has been seen in the 4 years and 9 mo nths since the second surgery. No adjuvant therapy was performed. Inguinal liposarcomas are relatively rare a:nd in most cases these tumors are though t to originate in the spermatic cord. The origin of the tumor is believed t o be the retroperitoneum.
