[Regular menstrual bleeding in a woman after hysterectomy]

The authors present a rare case of 39 years old woman, who had regular monthly bleedings mimicking menstruation during the two years after abdominal hysterectomy (without the adnexa). The woman was operated on in 1997 because of large uterine myoma and presented no other pathology in the abdominal cavity. She also suffered from autoimmunological anemia and chorea, which decreased her life activity and resulted in lack of gynecological care after the operation. The patient misunderstood the effect of surgery and mistook bleedings for signs of normal hormonal function. Deep external endometriosis of vaginal cuff and surrounding tissues was the cause of 'menstruation'. All this tissues were surgically removed. An immunological mechanism which plays role in endometriosis, chorea and anemia, was discussed.
