A rare case: Retroperitoneal liposarcoma

Retroperitoneal liposarcoma (RPLS) is the most common of the soft tissue sarcomas that arise in the retroperitoneum. These tumors reach a large size by time of diagnosis due to absence of symptoms in retroperitoneum. The definitive treatment of primary RPLS is com- plete surgical resection of the tumor but due to its proximity to critical anatomical organs, complete surgical resection of the tumor is difficult. At the same time, the high recurrence rate of RPLS is an important factor that complicates treatment. In this case report, we present RPLS measuring 20×18×19 cm in diameter. RPLS was detected in a 49-year-old male patient who complained of abdominal fullness. Recurrence developed despite complete surgical resection of tumor with spleen, left kidney and left adrenal gland. We also per- formed complete resection of recurrent tumor. Recurrence did not develop on follow-up of the patient for 1 year
