The histological landscape of the intrauterine polypoid masses.

The presence of intrauterine polypoid masses is a frequently encountered gynecologic pathology, usually associated with abnormal bleeding and infertility. We investigated a series of 857 consecutive patients with polypoid uterine masses that showed great histological variability. Although most lesions are benign lesions, the incidence of neoplastic lesions that can manifest macroscopically as polypoid masses increase with age. Heterogeneity of histopathological aspects of endometrial polypoid lesions requires a thorough differential diagnosis. [ABSTRACT FROM AUTHOR]
