Atypical polypoid adenomyoma of the uterus is a rare tumor and usually occurs in young women. The most common symptom is abnomal uterine bleeding and the definite diagnosis of the lesions depends on microscopic features. The treatment of this tumor depends on the age of the patient, her desire to retain reproductive function, and the severity of her symptoms. If the patient desires to preserve her reproductive capacity, repeated dilatations and curettages must be done because of the possibility of coexisting endometrial carcinoma. If not, hysterectomy is acceptable. We experienced a rare case of atypical polypoid adenomyoma of the uterus in a postmenopausal woman and report it with brief review of literature.
