title: Endometrial cancer implanted within a cesarean section scar.
abstract: Several reports have documented adenocarcinoma arising from endometriotic implants within cesarean section (C-S) scars on the serosal surface of the uterus; however, endometrial cancer invading the C-S scar from the uterine cavity has not been described. We report a case of a grade 1 endometrioid adenocarcinoma 'drop' lesion invading a previous C-S scar with resultant cervical stromal invasion. Using both MR images and a thorough review of the pathology, the tumor at the C-S scar was determined to be an implant derived from a primary lesion at the uterine fundus. With increases in the incidence of both endometrial cancer and births by C-S, it is likely we will encounter more cases of iatrogenic implants of endometrial cancers in C-S scars.
