Conclusions:
Retroperitoneal tumors constitute a heterogeneous group of uncommon neoplasms of unknown etiology. Liposarcoma is the most frequent lesion in this group. It is usually asymptomatic and is often identified by the presence of a large abdominal mass. It is considered to be a peculiar lesion because of its biological and morphological features and course.
