Xanthogranulomatous endometritis (XGE) or histiocytic endometritis is a chronic inflammatory pathology of rare presentation, characterized by an exaggerated inflammatory infiltrate that can mimic an endometrial carcinoma. We report two cases of this disease, one of them with a classic presentation of endometritis and the other one with a severe compromise in which the clinical presentation and imaging findings suggested a possible endometrial carcinoma. Knowledge of this unusual and rare pathology, including its etiopathogenesis, is important since it can be included in the differential diagnosis of endometrial carcinoma and, therefore, whenever it is found, to avoid excessive treatment.
