Endometrial intraepithelial neoplasia (EIN) is a premalignant lesion of the uterine lining that predisposes to endometrioid endometrial adenocarcinoma. It is composed of a collection of abnormal endometrial cells, arising from the glands that line the uterus , which have a tendency over time to progress to the most common form of uterine cancer ...
Pre-cancerous endometrial hyperplasias are also referred to as endometrial intraepithelial neoplasia. [41] Mutations in the KRAS gene can cause endometrial hyperplasia and therefore Type I endometrial cancer. [37] Endometrial hyperplasia typically occurs after the age of 40. [9]
High grade anal intraepithelial neoplasia. Progression of pancreatic intraepithelial neoplasia, including mutations. [1] Cervical intraepithelial neoplasia (CIN), spanning a bit more than 2/3 of the thickness of the cervical epithelium. Intraepithelial neoplasia (IEN) is the development of a benign neoplasia or high-grade dysplasia in an ...
Uterine clear-cell carcinoma (CC) is a rare form of endometrial cancer with distinct morphological features on pathology; it is aggressive and has high recurrence rate. Like uterine papillary serous carcinoma CC does not develop from endometrial hyperplasia and is not hormone sensitive, rather it arises from an atrophic endometrium.

Uterine adenomyoma, the localized form of uterine adenomyosis, is a tumor composed of endometrial gland tissue and smooth muscle in the myometrium. [2] Adenomyomas containing endometrial glands are also found outside of the uterus, most commonly on the uterine adnexa but can also develop at distant sites outside of the pelvis . [ 3 ]
Surface epithelial-stromal tumors are a class of ovarian neoplasms that may be benign or malignant. Neoplasms in this group are thought to be derived from the ovarian surface epithelium (modified peritoneum) or from ectopic endometrial or fallopian tube (tubal) tissue.
In the ovary, embryonal carcinoma is quite rare, amounting to approximately three percent of ovarian germ cell tumours. The median age at diagnosis is 15 years. Symptoms and signs are varied, and may include sexual precocity and abnormal (increased, reduced or absent) uterine bleeding.
