Background. When the diagnosis of atypical endometrial hyperplasia is based on the results of diagnostic curettage or aspiration biopsy of the endometrium, there is a chance that endometrial cancer will not be detected and it can influence approach to the patient. Objectives. To analyze the results of pathology findings after hysterectomy in patients referred with diagnosis of atypical endometrial hyperplasia. Method. Retrospective chart review. The pathology results of surgical treatment in 132 patients referred with diagnosis ofatypical endometrial hyperplasia for a period of 2005-2008 yr had been analyzed. Results. Post-operative findings were: endometrial cancer - in 19%, atypical hyperplasia - in 35%, simple and complex hyperplasia - in 33%, atrophic endometrial changes - in 13% of patients. The tumor was within the endometrium in 5 patients, the superficial invasion of the myometrium (1-2 mm) were in 8 patients, invasion to half of the myometrium layer - in 9 patients, invasion for more than half of the myometrium - in 3 patients. Conclusion. Discrepancy between diagnostic and postoperative histological findings from patients with atypical hyperplasia is relatively high. The approach to treatment of atypicalendometrial hyperplasia is under discussion.
