Abstract

A man in his 50s was redirected by his general practitioner to our University Hospital for a radiological evaluation after the complaint of a left inguinal swelling. The preliminary ultrasound and CT scan showed a left parafunicolar mass located between the root of the penis and the spermatic cord. The lesion was biopsied shortly after and histologically diagnosed as a dedifferentiated liposarcoma. The patient underwent a cycle of neoadjuvant radiotherapy, which proved to be ineffective. He was then subjected to an organ sparing surgical removal of the mass, followed by a second organ sparing removal of some residual disease. The last CT scan showed absence of the inguinal disease; however, lung and hepatic metastasis were detected, which are scheduled to be treated with a course of chemotherapy and radiofrequency.
