Laparoscopic resection of an obturator schwannoma: a case report

Schwannomas are usually benign tumors that arise from a nerve supporting the Schwann cells, those are mostly associated with the cranial or main peripheral nerves. The occurrence of retroperitoneal schwannoma is quite rare, and in such a case, surgical excision is the first option for treatment. In 1996, Melvin1 confirmed the feasibility of the complete resection of a retroperitoneal schwannoma using laparoscopy for the first time. Until recently, only few cases of laparoscopic resection of retroperitoneal schwannoma have been reported.
