Uncommon presentation of an abdominal wall tumor

Abdominal wall endometriosis (AWE) is a rare condition characterized by the precense of ectopic endometrial tissue in any segment of the abdominal wall, often associated with prior surgical interventions such as cesarean sections. We report a case of 47-year-old woman who presented with a four-year history of a painful, progressively enlarging mass on her lower abdomen, with pain exacerbated by her menstrual cycle.
