Extra-gonadal mature teratoma: A case report of retroperitoneal location with a literature review

Mohamed Farès Mahjoubi et al. Clin Case Rep. .

Abstract

Extra-gonadal mature teratoma is a benign tumor occurring rarely in adults. The retroperitoneal localization constitutes less than 4%. Treatment consists of surgical resection. Histological examination is essential for definitive diagnosis. We reported an unusual case of mature retroperitoneal teratoma discovered in a young man with abdominal pain.

Keywords: dermoid cyst; retroperitoneal space; teratoma.
