Endometrial adenocarcinoma arising in a secretory endometrium.

Endometrial adenocarcinoma in young women below the age of 45 years and in a functioning endometrium is rare. We present the case of a 41-year-old woman, who without clinical risk factors, was found to have a focal well-differentiated endometrial adenocarcinoma in the background of a histologically secretory endometrium. Endometrial evaluation for abnormal vaginal bleeding in a young ovulating female and thorough examination of the endometrium in its entirety in the hysterectomized uterus are reemphasized.
