DE LA PENA, Ada de la Concepción et al. Apropos of a case of retroperitoneal liposarcoma. Rev Cubana Cir [online]. 2008, vol.47, n.1. ISSN 0034-7493.

The retroperitoneal liposarcoma is a malignant tumor of mesenchymatous origin, and it is the most frequent of the sarcomas of soft tissues of retroperitoneal localization. Its growth is slow and insidious, which allows it to acquire large dimensions in an asymptomatic way. It is detected in the physical examination or by complementary tests. The case of a patient with a large irregular mass on the upper right half of the abdomen is presented. The results of the complementary studies suggesting the presence of a retroperitoneal tumor are showed. A well encapsulated tumor that was totally removed was found. The histological study confirmed a well differentiated retroperitoneal liposarcoma. The patient has had a satisfactory evolution during 2 years of follow-up
