Chorangioma is the most common benign tumor of placenta, with an incidence of approximately 1%. Tumors larger than 5 cm are associated with maternal and fetal complications. We report four cases of chorangioma that were identified in mostly primigravida (75%) with a mean gestational age of 33 wks (Range 28-33 wks). All except one case, complete placenta was received with mean weight of 550 g (Range 400-800 g) and tumor size of 9.4 cm (Range 0.5-23 cm). Microscopy showed capillary proliferation resembling fetal vessels in enlarged villi covered by trophoblastic epithelium. Three cases had preterm delivery. One also presented with abruptio placenta and intrauterine fetal death. Because of limited documentation of cases and dismal prognosis of these pregnancies, especially with large chorangiomas, it's of utmost importance to correctly diagnose them with the aid of color Doppler flow. In this series, 75% of cases (3/4), babies survived probably due to small size of tumor and attainment of fetal maturity.
Konjenital poş kolon, kalın bağırsağın tamamının veya bir kısmının, genellikle bir fistül yoluyla ürogenital sistem ile bağlantı kuran, kese benzeri bir dilatasyon ile yer değiştiği bilinmeyen bir embriyogenezisin nadir bir anorektal bozukluğudur. Bu durum Kuzey Hint popülasyonundaki erkekler arasında daha yaygındır ve uterovajinal malformasyonlar gibi çeşitli anomalilerle ilişkilidir. Yıllar içinde tip 4 gibi daha az ciddi tiplere doğru kayma gösteren beş tipe ayrılmıştır. Otopsi sırasında tanı alan 29 haftalık dişi fetüste fistülsüz anal agenezi ve alt vajinal agenezi ile görülen konjenital poş kolon olgusunu sunmayı amaçladık. Fistülün olmaması ve canlı doğumlarda bile göz ardı edilen vajinal agenezis ilişkisi olgumuzu değerli bir hale getirmektedir. Doğum öncesi erken tanı ve bu durum hakkında farkındalık uygun tedavi ve avantajlı cerrahi sonlanım için gereklidir.

This condition is more common among males in North Indian population and is associated with various anomalies such as uterovaginal malformations. It has been classified into five types that are showing a shift over the years towards less severe types such as type 4. We report a case of type 4 congenital pouch colon with anal agenesis without fistula and lower vaginal agenesis in a 29-week-old female fetus diagnosed during autopsy. The absence of a fistula and association with vaginal agenesis in a female fetus, which gets overlooked even in live births, makes it a unique case. Early prenatal diagnosis and awareness about this condition are essential for appropriate management and favorable surgical outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
