RENGIFO, Pablo; CARRASCO, Carlos  and  CACERES, Jaime. Giant Retroperitoneal Myxoid Liposarcoma: A case report. Rev Med Hered [online]. 2014, vol.25, n.2, pp.1-2. ISSN 1729-214X.

Liposarcoma is the most common retroperitoneal sarcoma. In Peru is only known the frequency of the Instituto Nacional de Enfermedades Neoplásicas, where it accounts for 33.7% of retroperitoneal sarcomas. The growth of this tumor is low, and it is associated with non-specific symptoms, including abdominal pain and increase in abdominal waist. CT-scan provides vital information for diagnosis. We report the case of a 34 year-old male patient who presented with a 8-month history of abdmominal pain, constipation and feeling of an intra-abdominal mass. The CT-scan revealed signs of a retroperitoneal mass with fat tissue densities (-53UH). Pathological diagnosis was dedifferentiated myxoid liposarcoma, which is infrequent in the retroperitoneum. We analyzed the retroperitoneal location and CT-scan features of this tumor.
