Endometrial adenocarcinoma usually occurs after menopause. This tumor is extremely rare in women younger than 30 years. Its treatment includes hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and in same cases, radiotherapy. We report a case of endometrial Adenocarcinoma in a 26-year-old patient. Through this case the authors emphasize the need of endometrial evaluation in young females with abnormal bleeding before starting any medical treatment. Specific problems of endometrial cancer at young age include delay in diagnosis, difficulty in pathologic interpretation of the curetting tissues and the motivation of most patients to preserve their fertility.
