[2] [3] The EIN diagnostic schema is intended to replace the previous "endometrial hyperplasia" classification as defined by the World Health Organization in 1994, which have been separated into benign (benign endometrial hyperplasia) and premalignant (EIN) classes in accordance with their behavior and clinical management.
Adenosarcoma (also Müllerian adenosarcoma) is a rare malignant tumor that occurs in women of all age groups, but most commonly post-menopause.Adenosarcoma arises from mesenchymal tissue and has a mixture of the tumoral components of an adenoma, a tumor of epithelial origin, and a sarcoma, a tumor originating from connective tissue.
Serous carcinoma is a Type II endometrial tumor that makes up 5–10% of diagnosed endometrial cancer and is common in postmenopausal women with atrophied endometrium and black women. Serous endometrial carcinoma is aggressive and often invades the myometrium and metastasizes within the peritoneum (seen as omental caking ) or the lymphatic system.
Carcinosarcoma of the uterus. In gross appearance, MMMTs are fleshier than adenocarcinomas, may be bulky and polypoid, and sometimes protrude through the cervical os.On histology, the tumors consist of adenocarcinoma (endometrioid, serous or clear cell) mixed with the malignant mesenchymal elements; alternatively, the tumor may contain two distinct and separate epithelial and mesenchymal ...
Endometrial cancer forms from the lining of the uterus, and uterine sarcoma forms from the muscles or support tissue of the uterus. [1] [2] Endometrial cancer accounts for approximately 90% of all uterine cancers in the United States. [6] Symptoms of endometrial cancer include changes in vaginal bleeding or pain in the pelvis.

There is an association with endometriosis and concurrent primary endometrial carcinoma (endometrial cancer). On gross pathological examination, the tumor is cystic and may be solid and some arise in cystic endometriosis. In 40% of cases, endometrioid tumors are found bilaterally. [3]

Definitive diagnosis is necessary to avoid unnecessary treatment and exclude more serious diagnoses (for example, haemoptysis, pleural effusion or cancer). Overall treatment for pulmonary endometriosis is surgical, with subsegmentectomy. Preserving lung parenchyma is a priority while removing macroscopic signs of pathological tissue. [5]
