Endometrial Polyps 

An endometrial polyp is a benign tumor consisting of surface endometrium lining three sides of the tumor, fibrous stroma, and thick-walled, centrally positioned blood vessels endometrial polyps. Recent studies from multiple laboratories report that clonal rearrangement of chromosome 6p21 is common in the mesenchymal (stroma) cells in the polyp. The endometrial cells do not have the chromosome 6 rearrangement.

Most endometrial polyps are solitary. In approximately 20% of cases multiple polyps are present. Polyps peak between ages 40 and 50 years, but many cases occur in menopausal women. In fewer than 1% of cases, polyps are associated with cancer. The usual presenting symptom is intermenstrual bleeding.

Polyps are typically diagnosed by sonography (especially sensitive in the follicular phase), saline infusion hysterosonography, hysterosalpingography, hysteroscopy, or curettage. Curettage often fails to remove endometrial polyps because of the mobility.

Other Benign Uterine Disorders

Adenofibromas are benign tumors of epithelium and stroma that contain fewer that 4 mitoses per 10 high-power fields. Women with adenofibromas usually are elderly. Abnormal vaginal bleeding is common.

Uterine Conservation at the Time of Adnexal Removal

In women who desire future childbearing, every effort should be made to preserve ovarian tissue unless a cancer diagnosis necessitates the removal of both ovaries. Occasionally, the clinician is confronted with a large benign ovarian cyst and must decide whether to remove the entire ovary or perform a cystectomy. If the woman has a desire for more children, an effort should be made to perform a cystectomy and to leave as much ovarian tissue.

For some conditions, both ovaries require surgical removal. The clinician then is confronted with the issue of uterine conservation. If the woman has clearly and consistently communicated that she has no interest in further pregnancies and does not desire to retain her uterus, the uterus can be removed. If the woman has clearly expressed an interest in future childbearing, the uterus may be left in place so she may be able to become pregnant through oocyte or embryo donation.
