Mature teratoma of the fallopian tube is extremely rare. Most cases are incidentally diagnosed as originating from the fallopian tube following cesarean section, diagnostic laparoscopy, or examination of a surgical specimen. Here, we present a case of mature teratoma of the fallopian tube identified during laparoscopic surgery. A 5-cm mature teratoma was detected in the pelvic cavity of a 30-year-old Filipino female using transvaginal ultrasonography, computed tomography, and magnetic resonance imaging (MRI). Laparoscopy revealed a cystic tumor arising from the isthmus of the right fallopian tube, macroscopically distinct from the normal right ovary. The patient underwent laparoscopic right salpingectomy. Histologic analysis confirmed a benign, mature teratoma of the fallopian tube. Gynecologic surgeons should be aware of this rare entity, as it may be encountered incidentally during surgery and influence intraoperative decision-making.
输卵管成熟畸胎瘤极为罕见。大多数病例是在剖宫产、诊断性腹腔镜检查或手术标本检查后偶然诊断为起源于输卵管。在此，我们报告一例在腹腔镜手术中发现的输卵管成熟畸胎瘤病例。一名30岁的菲律宾女性经阴道超声、计算机断层扫描和磁共振成像（MRI）检查，在盆腔内发现一个5厘米的成熟畸胎瘤。腹腔镜检查显示一个囊性肿瘤起源于右侧输卵管峡部，肉眼可见与正常右侧卵巢不同。患者接受了腹腔镜下右侧输卵管切除术。组织学分析证实为良性的输卵管成熟畸胎瘤。妇科外科医生应了解这种罕见情况，因为它可能在手术中偶然遇到并影响术中决策。
