title: [A case of complex endometrial hyperplasia with atypia treated by microwave endometrial ablation].
abstract: Complex endometrial hyperplasia with atypia (CEHA) often precedes an endometrial carcinoma. A nulli-gradiva woman at high risk due to various complications underwent microwave endometrial ablation (MEA) at a frequency of 2.45 GHz for treatment of CEHA as an alternative to hysterectomy. The endometrium near the internal orifice was conserved to avoid hematometra. Endometrial biopsy specimen from the neighborhood of the internal orifice did not show any signs of endometrial hyperplasia postoperatively. Two years after the operation, endometrial biopsy revealed recurrence. The second MEA was performed. MRI one month after the second operation revealed that the uterine lining was completely replaced by avascular area without signs of regrowing endometrium or endocevix. Eighteen months have passed without recurrence.
