Myxoid liposarcoma is a soft tissue tumor that tends to occur in the limbs (especially the thigh) of patients ranging in age from 35 to 55 years. It is defined by the presence of a hypocellular spindle cell proliferation set in a myxoid background, often with mucin pooling. Lipoblasts tend to be small and often monovacuolated and to cluster around vessels or at the periphery of the lesion (review by Dei Tos, 2000).
