Giant Retroperitoneal Liposarcoma with Multi-Organ Involvement

Retroperitoneal liposarcomas are very rare tumors with poor prognosis. The diagnosis can be delayed since there are no specific symptoms and findings. Surgical resection is the primary treatment choice. Obtaining negative surgical margins should be the primary aim., Multiple organ resections may be essential in cases with huge liposarcoma and incomplete resection leads to local recurrences. There is still an ongoing controversy in the medical treatment of liposarcoma. In this study we presented a patient with liposarcoma who was advised for surgery due to retroperitoneal mass 2 years ago but refused so the mass grew to a huge size invading left kidney, left adrenal gland and left mesocolon. We aimed to point out organ invasion and huge masses of liposarcoma are not contraindications for resection, and resections of these huge tumors improve quality of life. All retroperitoneal masses should be aggressively excised and patients should be closely followed up.
