Abstract
Schwannomas usually occur in adults being between the second and fifth decades, and such neoplasms are extremely rare in a pediatric population. In addition, they are not normally found in the retroperitoneal region. Here, we present a pediatric case of a retroperitoneal schwannoma in an adrenal location where the tumor was not able to be preoperatively differentiated from other benign or malign adrenal gland tumors. In our opinion, this tumor can be included in the differential diagnosis of a nonfunctioning retroperitoneal adrenal mass in children.
