Abstract

Background: Schwannomas which are derived from Schwann cell and strictly found in head or neck region, upper and lower limbs. Retroperitoneal location accounts for less than 3% of primary schwannoma. We present a case of huge retroperitoneal schwannoma treated using 3D laparoscopy.

Case Report: A 36 years-old gentleman was referred to our clinic due to suspected renal lesion. After imaging, a huge retroperitoneal tumor was noted on CT scan. Due to suspected sarcoma, surgical intervention was performed. The final pathology showed Antoni A and B section along with S100 and SOX-10 positive, therefore a diagnosis of benign schwannoma was given.

Discussion: A variety of diagnosis can arrive from retroperitoneum tumor, ranging from sarcoma to lymphoma. The size of tumor, the clinical symptoms, the involvement of peripheral organ along with selective pre-operative biopsy will help determine the treatment course of these patients. Pre-operative biopsy should be considered in selected individuals to help with decision making and avoid any unnecessary surgery.

Conclusion: A careful pre-operative survey and selective biopsy is warranted for patients with retroperitoneal tumor.
