Objective: We report a new case of benign retroperitoneal schwannoma arising from the adrenal gland.
Methods: 53 year old male with history of moderate benign prostatic hyperplasia under alpha blocker therapy who referred right flank discomfort for two months prior to last visit, without any other symptoms; radiologic examination with Ultrasound and CT scan and preoperative endocrine study were suggestive of non functioning adrenal tumour which was surgically extirpated.
Results: Anatomopathological report showed a benign juxta-adrenal schwannoma.
Conclusions: It is an uncommon retroperitoneal tumour. The presence of cystic changes within a retroperitoneal tumour is relatively frequent in schwannomas and may suggest its diagnosis. The case we report did not have cystic structures.
