[Retroperitoneal schwannoma: a case report]

Schwannomas are degenerate peripheral nerve sheath tumors that very rarely occur in the retroperitoneum. They are usually benign than malignancy is very rare and is usually observed in patients with von Recklinghausen disease. We report a case of female adult patient who presented with vague abdominal discomfort. The preoperative diagnosis was difficult and the treatment was complete surgical excision. The patient is with no evidence of recurrence more than four years after surgery.
