Introduction: Teratomas are congenital tumors consisting of derivatives from the ectoderm, endoderm and mesoderm germ cell layers. A teratoma is considered to be a non-seminomatous germ cell tumor and is typically located in either the sacrococcygeal region or in the gonads. Giant retroperitoneal teratomas in adults are even rarer, with only a few cases previously described in the literature. 
Case report: A 35-year-old male patient with severe nausea and vomiting was taken to the emergency ward of Hamadan Be’sat Hospital.
