Mature cystic teratoma is the most common type of ovarian tumor in children. Adnexal torsion is the main complication of mature ovarian teratoma. The synchronous bilateral incidence of mature cystic teratoma in premenarchal girls is known to be rare. However, the incidence of adnexal torsion is higher in young girls. A 10-year-old girl presenting with acute abdomen was managed by emergency laparotomy. Bilateral mature ovarian teratoma with adnexal torsion of the right ovary was found. The right ovarian tissue was not viable due to torsion and an oophorectomy was necessary. Cystectomy with preservation of the ovarian tissue of the left ovary was performed. Histopathological diagnosis was bilateral synchronous mature teratoma with necrosis of the right adnexa. Although the risk of malignancy of torsed ovaries and mature teratomas in premenarchal girls is low, their removal is recommended to prevent adnexal torsion. Decision between ovarian tissue sparing surgery or oophorectomy depends on the risk of malignancy, fertility preservation and the avoidance of early menopause.

OBJECTIVE: We sought to evaluate the distribution of scavenger receptor for hemoglobin positive (CD163(+)) cells in the placenta and fetal membranes from pregnancies complicated by preterm prelabor rupture of membranes with respect to the presence and absence of histological chorioamnionitis. METHODS: Sixty-two women with singleton pregnancies with a gestational age between 24+0 and 36+6 weeks were included in a prospective cohort study. CD163 was evaluated by immunohistochemistry in the placenta and fetal membranes. The number of CD163(+) cells and neutrophils was counted in the following locations: fetal membranes' amnion, chorion, and decidua, as well as the placenta's amnion, chorionic plate, subchorionic fibrin, stem villi, terminal villi, and decidua. RESULTS: CD163(+) cells were found in all compartments of the placenta and the fetal membranes regardless of the inflammatory status. A positive correlation between the number of CD163(+) cells and neutrophils in the subchorionic fibrin and the chorionic plate was found. The number of CD163(+) cells was higher in the placental subchorionic fibrin and chorionic plate when histological chorioamnionitis was present. CONCLUSION: The presence of histological chorioamnionitis affected the number of CD163(+) cells in the placental chorionic plate and in the subchorionic fibrin but not in the fetal membranes.
