Abstract

Background: Placental chorangioma is a benign angioma arising from chorionic tissue. These are well demarcated placental mass composed of capillaries, stromal cells and surrounding trophoblast arising in a stem villus. Case report: A 28-year-old, gravida 2 para 1, L1 was admitted for abdominal pain, vaginal bleeding and foul smelling discharge. She had history of normal vaginal delivery at home two month back. On per vaginal examination cervix dilated, foul smelling discharge was noted. Clinically suspected of retained placenta, placenta increta. USG abdomen and pelvis showed an enlarged uterus with a focal heterogeneously hyperechoic lesion measures 44x23x34mm noted in the upper endometrial cavity. Moderate increase vascularity in color doppler examination. The findings likely placental remains (? Placenta increta) / retained product of conceptions. No pelvic mass was seen. Hysterecscopy with dilation and curettage were done for removal of retained products. On gross pathological examination single, rounded, well demarcated placental mass was seen. It was firm, reddish brown in color with localization on the fetal side of the placental disk. On histopathology reported as placental chorangioma cellular subtype. Chorioamnitis was noted. Areas of degenerative changes, necrosis, focal calcification, and hyalinization was noted. Conclusion: Placental chorioangioma is a rare benign tumor of the placenta. Early diagnosis, close prenatal checkup and monitor with appropriate intervention may prevent severe fetal and maternal complications and perinatal mortality related to chorioangioma.
