Giant primary retroperitoneal teratoma in an adult male: A rare entity

Abstract

Introduction: Primary and giant retroperitoneal teratoma is a rare entity in adults which occurs more commonly in females than males. Case Report: Herein, we describe an unusual case of a 28-year-old male patient referred to our hospital for a retroperitoneal tumor diagnosed by computed tomography scan and confirmed by histological examination as a retroperitoneal teratoma. Surgical excision was performed. The patient is doing well after 26 months of follow-up. Conclusion: Primary retroperitoneal teratoma is a rare entity in adults. Preoperatively, the diagnosis can be established by its characteristic appearance on computed tomography scan. Surgery is the mainstay of treatment and the prognosis is excellent for benign retroperitoneal teratoma if complete resection can be accomplished.
