Abstract: Objective：To summarize and analyze the clinical features and diagnosis of tubal teratoma. Methods：4 cases of tubal teratoma in our hospital from 2010 to 2017 years and 25 cases reported in domestic literature were analyzed retrospectively. Results：The average age of 29 cases of tubal teratoma was 35.17 (24～60) years age, and the pregnancy history was 86.96%. The tumors occurred in the left side, 55.17%, the right side, 44.83%, and 72.41% in the fimbria and ampulla. The size of the tumor was between 0.3～15 cm, and 6～10 cm accounting for 55.17%. Abdominal pain and pelvic mass account for 72.41%. No cases were diagnosed before operation, 5 cases were reversed, and 3 cases were infertile. Mature teratoma accounted for 89.66%. Of 4 cases in our hospital, 2 underwent tubal mass stripping. The follow-up after stripping (1 cases followed up for 6 years, 1 cases followed up for 29 months) showed no tumor recurrence, and one of them was subsequent pregnant after 3 months, and 1 case was not pregnant so far. Conclusions：The clinical features of tubal teratoma are nonspecific and easily misdiagnosed. There are torsion, malignant change, infertility and other risks, treatment should be timely.
