Abstract: Teratoma is neoplasia originating from a germ cell, which usually contains identifiable tissue derived from all three germ cell layers. The presence of teratoma is due to an organ being affected by a tumor, which generally occurs in ovary. Teratoma is also seen occasionally in some extragonadal organs. However, a primary teratoma in the bladder is a rare entity. We hereby present a case of bladder teratoma. A 53-year-old woman whose chief complaints were urinary interruption, pilimiction, and a stone in her urine was diagnosed by cystoscopy and received rehabilitation after tumor resection surgery. She was then symptom-free and further follow-up observation was in progress. We also include a literature review concerning primary bladder teratoma.
