Liposarcoma is an extremely rare malignant adipose mesenchymal tumor. World Health Organization classifies liposarcomas into five subtypes: well differentiated, myxoid, pleomorphic, dedifferentiated and mixed. The association between multiple and synchronous location of several subtypes of liposarcomas is exceptional. Only 34 cases have been reported in the literature. We report the case of synchronous association between retroperitoneal dedifferentiated liposarcoma and two small well-differentiated lipoma-like pericolic liposarcomas. Anatomopathological aspects, therapeutic options and prognostic factors of liposarcomas have been reviewed in this study.

UI	MeSH Term	Description	Entries
D008080	Liposarcoma	A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces.
