Abstract：
Cesarean scar ectopic pregnancy (CSEP) is a very rare form of ectopic pregnancy in which implantation occurs at the site of the previous cesarean scar with low or absent beta-human chorionic gonadotropin (hCG) levels. It has various differential diagnoses on gross and microscopic examination. A delay in the identification and management of this condition may lead to life-threatening complications. Here, we discuss the incidence and clinicopathological features of chronic CSEP, its types, and differential diagnoses.
