Trial of labor can be offered to all the women with low-lying placenta except for those accompanied by marginal sinus.

Immunoglobulin G4-related disease (IgG4-RD) is characterized by extensive infiltration of IgG4(+) plasma cells and fibrosis in various organs. However, the involvement of the ovary in IgG4-RD has never been reported. A 59-year-old woman presented with urinary retention. Magnetic resonance imaging and computed tomography revealed a huge multinodular pelvic mass and common iliac/para-aortic lymph node swelling. A laparotomy was performed under the suspicion of advanced ovarian cancer, and the pelvic mass was identified as ovary in origin. Histopathology of the excised tumor revealed massive lymphoplasmacytic infiltration (>90% were IgG4(+) plasma cells), storiform fibrosis, and obliterative phlebitis; thus leading to a diagnosis of IgG4-RD. We conclude that IgG4-RD can present as a bilateral ovarian mass along with lymphadenopathy, therefore mimicking ovarian cancer.

Simple aerobic bacterial culture of the vaginal swab sampled at the time of cerclage could be used as a reliable test to predict subsequent preterm delivery before 34 gestational weeks.

Mesonephric-like adenocarcinoma (MLA) is a rare tumor that occurs in the uterine endometrium and ovary. It morphologically and immunohistochemically resembles cervical mesonephric adenocarcinoma (MA).Here, we present a case of MLA of the ovary along with a literature review. An asymptomatic 84-year-old woman presented with a pelvic mass, detected by computerized tomography. Magnetic resonance imaging demonstrated a polycystic mass with a solid component in the left adnexal region. The solid component showed low signal intensity on T2-weighted imaging and high signal intensity on diffusion-weighted imaging. We strongly suspected an ovarian malignant tumor; therefore, surgical resection of the uterus and adnexa was performed. Macroscopically, the tumor was predominantly solid with yellowish-tan cut surface. Microscopically, it showed a tubular pattern with intraluminal colloid-like material resembling MA. The tumor cells were negative for estrogen receptor, calretinin, and CD10 and positive for PAX8 and TTF-1. These findings are consistent with those of MLA.

Twin vaginal deliveries were associated with slightly but significantly lower UmA-pH of the second twin, whereas twin cesarean delivery was associated with significantly larger intrapartum blood loss. Not only the neonatal risk but also the maternal risk should be taken into account when an optimal delivery mode for the twin pregnancy is considered.
