症例報告 腹腔鏡下子宮全摘術の際に予防的卵管摘出を行い、左卵管采に稀な頸管内膜症を認めた1例 2022 年 38 巻 1 号 p. 93-96 詳細 抄録 Endocervicosis is defined as an abnormal proliferation of tissues that histologically appear similar to the cervical tissues in other organs. While endocervicosis is less prevalent, it is most often found in the bladder. Herein, we present a rare case of endocervicosis in the left fallopian tube that was resected with total laparoscopic hysterectomy and prophylactic bilateral salpingectomy. Case: A 47-year-old woman, gravida 3 para 1, with a history of abdominal myomectomy, experienced menorrhagia and iron deficiency-related anemia owing to adenomyosis and leiomyoma. Ultrasound and magnetic resonance imaging showed adenomyosis, leiomyoma, and normal bilateral ovaries. We decided to perform laparoscopic total hysterectomy based on the indication of adenomyosis with menorrhagia and prophylactic bilateral salpingectomy for ovarian cancer prevention after obtaining the patient's informed consent. A laparoscopic examination showed that the uterine corpus with adenomyosis had adhesions with the omentum, and the bilateral ovaries and fallopian tubes were grossly normal with no peritoneal lesions. The histopathological analysis showed that the uterine adenomyosis histologically appeared similar to the endocervical-type glands in the fimbria of the left fallopian tube. Therefore, endocervicosis was diagnosed. Conclusion: We herein present an extremely rare case of endocervicosis of the fallopian tube that was resected with total laparoscopic hysterectomy. © 2022 日本産科婦人科内視鏡学会
