Endometrial polyp size and polyp hyperplasia.
OBJECTIVE
To assess the correlation between the size of endometrial polyps and the histopathologic diagnosis of hyperplasia or cancer.


METHODS
A retrospective study was conducted using databases of the outpatient clinic at Antonio Pedro University Hospital in Niterói, Brazil, and of a private hysteroscopy service. The analysis included 1136 asymptomatic patients with an endometrial polyp identified on hysteroscopy, with pathologic examination, during the period 1999-2012. The polyp size, the patients' age, the indication for hysteroscopic examination, and the use of hormone medication were compared with the finding of hyperplasia in the pathologic examination.


RESULTS
Only polyp size showed statistical significance among the variables analyzed (P<0.05). Endometrial polyps greater than 15mm showed a hyperplasia rate of 14.8%, compared with 7.7% in the group with smaller polyps (P<0.05).


CONCLUSIONS
Endometrial polyps measuring more than 15mm were associated with hyperplasia.
