“…Large vessels are located within the polyp. In women, polyps can have diverse patterns related to hormone status, and these lesions are classified morphologically according to the epithelial component (Mazur and Kurman 2005; Ramirez and Lawrence 2003). Because focal glandular proliferations are often identified at the base of the lesions, endometrial polyps are thought to arise from hyperplasia of the basalis layer (the endometrial layer that is not shed during menstruation) in women (Kurman 1994), although molecular studies have shown that karyotypically aberrant cells belong to the stromal component of endometrial polyps (Dal Cin et al 1998).…”

Endometrial stromal polyps (ESP) are a common spontaneous reproductive tract lesion in the female rat. However, there is limited information concerning the etiology, biology, and significance of these polyps as an end point in toxicology and carcinogenicity studies. This paper reviews relevant literature to address these aspects of ESP with respect to potential relevance to human uterine tumors. Endometrial stromal polyps in rodents appear as age-related lesions. There are only a few chemicals tested for carcinogenicity in rat and mouse cancer bioassays associated with increased incidence of ESP with no common characteristics or mechanism of action. Uterine endometrial polyps that occur in women and the uterine stromal polyps that occur in rodents have distinct characteristics, although both types of uterine lesions are common, benign, and noncancerous. Human endometrial polyps develop from both endometrial and stromal components, whereas rodent polyps develop from the stromal component of the uterus. Endometrial polyps in women are hormone sensitive, but there is no scientific or experimental evidence to date that suggests that uterine stromal polyps in rodents are hormone sensitive. Therefore, based on differences in their etiology and biology, endometrial stromal polyps observed in rodent toxicity and carcinogenicity studies appear to have limited relevance to human endometrial polyps occurring in women.
