Giant retroperitoneal liposarcoma.

BACKGROUND

Liposarcoma is the most frequent histopathological variety of the retroperitoneum, surgery is the gold standard for treatment.

CASE PRESENTATION

We present the case of a 24-year-old male who was diagnosed with a giant retroperitoneal liposarcoma. The patient received palliative treatment due to non-resectability on the basis of chemotherapy. We decided to perform surgery after no benefit was received with systemic treatment. Complete macroscopic resection of the tumor was performed, without multi-organ resection. The patient is currently alive and disease free at 14 months of evolution.

CONCLUSION

Retroperitoneal liposarcomas represent a unique situation and require a more aggressive surgical approach including multiple resections for recurrences. Based on the ability of the patient to tolerate the procedure, surgery is suggested to evaluate resectability of the tumor. We must take into consideration whether prolonged survival will be attained and tumor removal will result in palliation of symptoms.
