Retroperitoneal ganglioneuroblastoma with postoperative stress ulcer perforation in an adolescent: A case report and review of the literature.

Ganglioneuroblastoma (GNB) is a condition belonging to the neuroblastoma family. It is a transitional tumor consisting of a mixture of mature ganglioneuromas and malignant neuroblastomas. Its biological behavior is intermediate between benign and malignant, with a risk of recurrence and metastasis. It usually occurs in pediatric patients aged <10 years, particularly between the ages of 1 and 2 years, but may also occur in adolescents or adults. The present study reported on the clinical management of a case of postoperative stress ulcer with perforation in a 17-year-old female patient with retroperitoneal GNB and provided a review of the literature on retroperitoneal GNB in adolescents and adults.
