Intraoperative exploration revealed a teratoma in the utero-rectal fossa, adherent to the posterior uterine wall, right adnexa, and mesentery (A). The teratoma was disconnected from the posterior uterine wall, right adnexa, and mesentery (B). Gross observation of the specimen (C).

The surface of the mass was smooth, without obvious connection with the uterus and bilateral appendages, but its back was tightly adhered to the posterior wall of the uterus, the right appendages, and the mesentery (Figure 1A). We used scissors to separate the adhesion between the mass and its surrounding tissues (Figure 1B) until the mass was completely isolated (Figure 1C).
The specimen contains hair, bone, and tooth-like tissues (A). The pelvis and bilateral adnexal areas after complete resection of the teratoma showed no obvious abnormality (B). Histological pictures (C).

Yellow liquid flew out after the mass was cut and contained hair, bone, and tooth-like tissues (Figure 2A). Both ovaries were regarded normal considering the patient's age (Figure 2B). Pathological examination after surgery showed that the tumor was mature cystic teratoma (Figure 2C).
