Endometriosis in Obstetric Surgical Scars- A Case Report

Endometriosis is defined as a disease characterized by presence of tissue that is morphologically and biologically similar to normal endometrium, and contains functional endometrial glands and stroma, in ectopic locations outside the uterine cavity. Endometriosis can sometimes occur in a previous surgical scar. Scar endometriosis is rare and difficult to diagnose. It mostly follows obstetrical and gynecological surgeries. This condition is often confused with other surgical conditions. We are reporting two cases of scar endometriosis following cesarean section and episiotomy. Both the patients presented with a painful palpable mass which were excised and the histopathological examination confirmed the diagnosis. Clinical suspicion is often enough to clinch the diagnosis. Lack of awareness of this condition makes the preoperative diagnosis difficult.
