Primary retroperitoneal liposarcomas extending into the inguinal canal are rare. We present the case of a large retroperitoneal liposarcoma invading the left testicle and its spermatic cord. It was diagnosed by imaging as a large mass that compresses surrounding abdominal structures and communicating with the inguinal canal. A surgical intervention consisting of en bloc resection of the tumor and the left testicle with its cord was performed by 2 routes, intercostal and inguinal. Histology showed a dedifferentiated liposarcoma, which is a rare entity with a high rate of malignancy and a poor prognosis. The treatment of choice is wide surgical resection with clear margins; chemotherapy and radiotherapy are less sensitive. The patient did not manifest any particular complaints during the first six months after surgery.<\/jats:p>","DOI":"10.1093\/jscr\/rjad162","type":"journal-article","created":{"date-parts":[[2023,5,25]],"date-time":"2023-05-25T14:29:36Z","timestamp":1685024976000},"source":"Crossref","is-referenced-by-count":3,"title":["A
