Decidual change is a key process required by the uterus to make itself ready for implantation. Presence of ectopic decidual tissue outside the uterine cavity is known as deciduosis. The clinical presentation can vary from being totally asymptomatic and subtle to presenting in the form of life-threatening emergencies like hemoperitoneum, recurrent pneumothorax, or even bowel perforation. Here, we present a case of ectopic deciduosis of cervix presenting in the form of severe life-threatening antepartum hemorrhage in second trimester of pregnancy.
