Leiomyoma enucleated from a uterus. External surface on left; cut surface on right. Micrograph of a small, well-circumscribed colonic leiomyoma arising from the muscularis mucosae and showing fascicles of spindle cells with eosinophilic cytoplasm and elongated, cigar-shaped nuclei Immunohistochemistry for β-catenin in uterine leiomyoma, which is negative as there is only staining of cytoplasm ...
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 ...
Uterine serous carcinoma is a malignant form of serous tumor that originates in the uterus. It is an uncommon form of endometrial cancer that typically arises in postmenopausal women. It is typically diagnosed on endometrial biopsy , prompted by post-menopausal bleeding .
Premalignant lesions are morphologically atypical tissue which appear abnormal when viewed under the microscope, and which are more likely to progress to cancer than normal tissue. [7] Precancerous conditions and lesions affect a variety of organ systems, including the skin, oral cavity, stomach, colon, lung, and hematological system.
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.
Symptoms: Endometrial cancer: vaginal bleeding, pelvic pain [1] Uterine sarcoma: vaginal bleeding, mass in the vagina [2] Types: Endometrial cancer, uterine sarcoma [3] Risk factors: Endometrial cancer: obesity, metabolic syndrome, type 2 diabetes, tamoxifen use, unopposed estrogens, late menopause, family history of the condition [1]
Other symptoms include pain with urination, pain during sexual intercourse, or pelvic pain. [1] Endometrial cancer occurs most commonly after menopause. [2] Approximately 40% of cases are related to obesity. [3] Endometrial cancer is also associated with excessive estrogen exposure, high blood pressure and diabetes. [1]
For example, a lipoma is a common benign tumor of fat cells , and a chondroma is a benign tumor of cartilage-forming cells (chondrocytes). Adenomas are benign tumors of gland-forming cells, and are usually specified further by their cell or organ of origin, as in hepatic adenoma (a benign tumor of hepatocytes, or liver cells).
