Mature cystic teratomas are the most common among all ovarian neoplasms, representing 30-40% of the cases. However, to the best of our knowledge, there have been only two reports of mature cystic teratomas occurring in identical twins to date. We herein report a case of identical twins with mature cystic teratomas who were treated with laparoscopic surgery. A 32-year-old woman was referred to our hospital due to a tumor in the right ovary. The patient underwent laparoscopic resection of the ovarian tumor and the pathological diagnosis was benign mature cystic teratoma. Two years later, the identical twin of the abovementioned patient was referred to our hospital also due to a right ovarian tumor. The patient underwent laparoscopic resection of the ovarian tumor and the pathological diagnosis was benign mature cystic teratoma. Therefore, for early diagnosis, it may be important to consider the possibility of mature cystic teratoma in the identical twin of a patient, even in the absence of symptoms.
成熟囊性畸胎瘤是所有卵巢肿瘤中最常见的，占病例的30%-40%。然而，据我们所知，迄今为止仅有两例成熟囊性畸胎瘤发生在同卵双胞胎中的报道。我们在此报告一例接受腹腔镜手术治疗的同卵双胞胎患成熟囊性畸胎瘤的病例。一名32岁女性因右侧卵巢肿瘤被转诊至我院。患者接受了卵巢肿瘤的腹腔镜切除术，病理诊断为良性成熟囊性畸胎瘤。两年后，上述患者的同卵双胞胎也因右侧卵巢肿瘤被转诊至我院。患者接受了卵巢肿瘤的腹腔镜切除术，病理诊断为良性成熟囊性畸胎瘤。因此，对于早期诊断而言，即使患者没有症状，考虑其同卵双胞胎患成熟囊性畸胎瘤的可能性可能也很重要。
