The incidence of monodermal teratomas of the reproductive system is low, and most doctors lack adequate understanding, which can easily lead to missed diagnoses and/or misdiagnosis. Therefore, it is important to fully understand the clinical characteristics, diagnosis, differential diagnosis, and treatment of monodermal teratomas of the reproductive system.
Case 1: A 14-year-old boy was admitted to the hospital with a right testicular mass for 1 wk and underwent surgical resection. He was finally diagnosed with right testicular monodermal teratoma with no special postoperative discomfort. Case 2: A 40-year-old woman was admitted to the hospital for uterine abnormalities indicated by ultrasound 20 d prior and underwent laparoscopic surgery. She was finally diagnosed with a left ovarian monodermal teratoma with a satisfactory postoperative quality of life. Case 3: A 49-year-old woman was admitted to the hospital with a pelvic mass that was discovered on B-ultrasound a week prior and underwent laparoscopic resection of the left adnexa. She was finally diagnosed with left ovarian monodermal teratoma, and her postoperative quality of life was satisfactory.
Monodermal teratoma is a rare tumor whose clinical manifestations are primarily benign. Simple surgical resection of the tumor is effective.
生殖系统单胚层畸胎瘤的发病率较低，多数医生对此认识不足，容易导致漏诊和/或误诊。因此，充分了解生殖系统单胚层畸胎瘤的临床特点、诊断、鉴别诊断及治疗方法具有重要意义。
病例1：一名14岁男孩因右侧睾丸肿物1周入院，接受了手术切除。最终诊断为右侧睾丸单胚层畸胎瘤，术后无特殊不适。病例2：一名40岁女性因20天前超声提示子宫异常入院，接受了腹腔镜手术。最终诊断为左侧卵巢单胚层畸胎瘤，术后生活质量良好。病例3：一名49岁女性因1周前B超发现盆腔肿物入院，接受了左侧附件腹腔镜切除术。最终诊断为左侧卵巢单胚层畸胎瘤，术后生活质量良好。
单胚层畸胎瘤是一种罕见肿瘤，临床表现多为良性。单纯手术切除肿瘤有效。
