Nonpuerperal Uterine Inversion Associated With an Immature Teratoma of the Uterus in an Adolescent

BACKGROUND: We report a case of nonpuerperal uterine inversion associated with an immature teratoma of the uterus. CASE: An adolescent nullipara with prolonged vaginal bleeding, severe abdominal pain, symptomatic anemia, and a presumed diagnosis of retained products of conception was found to have a large mass in the vagina. Uterine inversion was diagnosed and corrected using the Haultain procedure. The inversion catalyst was found to be an immature teratoma of the uterus. CONCLUSION: Reproductive age women with the rare finding of nonpuerperal uterine inversion are likely to have a malignancy. However, uterine-sparing surgery to correct the inversion should be attempted in young women until final pathology is known.
