Histopathological evaluation of intrauterine polyps and scrapings of the uterine cavity in women with endometrial polyp described in ultrasound.

OBJECTIVES: The aim of the study was to analyze the histopathology results of polyps removed and scrapings taken from the uterus in women, in whom ultrasound described endometrial polyp.

METHODS: The study included 412 patients whose ultrasound described endometrial polyp in the uterine cavity. The material obtained during hysteroscopy or curettage of the uterine cavity were subjected to the histological evaluation. The study group was divided into two subgroups depending on the presence of symptoms. The analysis of the relationship between variables was performed using Student's t-test and the Mann-Whitney U test.

RESULTS: In our study of 412 patients with suspected endometrial polyp based on ultrasound 342 patients had mild lesions in the uterine cavity, including a 51 of women had mild hyperplasia, 14 of women had endometrial hyperplasia with atypia or endometrial cancer. Subgroup of women who report abnormal bleeding accounted for 49.8% study group, asymptomatic patients was 50.2%.

CONCLUSIONS: This study showed no higher incidence of precancerous lesions and cancers of the endometrium in women with endometrial polyp described in ultrasound, who reported abnormal bleeding. Ultrasound-based diagnosis of endometrial polyps should therefore be verified both in women who report abnormal bleeding, as well as in asymptomatic women.
