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).
Similarly, sun or especially UV exposure is an important risk factor for both actinic keratosis which can progress into melanomas [10] as well as skin cancer. Smoking is a risk factor for premalignant (as well as malignant) lung lesions. Hereditary conditions that are risk factors to cancer can also be risk factors to premalignant lesions.
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 ...
Management of GTN requires pathology review, treatment options and monitoring of hCG. Therefore, it can be treated with curettage, hysterectomy and single agent or multi agent chemotherapy. [ 4 ] Although this group of diseases are highly susceptible to chemotherapy, prognosis depends on the type of GTN and whether the tumor has spread to other ...
A neoplasm can be benign, potentially malignant, or malignant . [9] Benign tumors include uterine fibroids, osteophytes, and melanocytic nevi (skin moles). They are circumscribed and localized and do not transform into cancer. [8] Potentially-malignant neoplasms include carcinoma in situ. They are localised, and do not invade and destroy but in ...
Treatment of uterine cancer may differ depending on the type of cancer and staging of the tumor. [15] In early stages, minimal invasive surgery is preferred. [16] For endometrial cancer, five main types of treatments are used, including surgery, radiation therapy, chemotherapy, hormone therapy, and targeted therapy
Uterine adenosarcoma have, by definition, a malignant stroma and benign glandular elements. The World Health Organization (WHO) criteria have a mitotic rate cut point; however, this is often disregarded, as bland-appearing tumours with a low mitotic rate are known to metastasize occasionally.
The use of this treatment type largely depends on the fact that malignant and normal cells have differing responses to the energy source used. [21] This dependency is due to the intracellular changes which occur during hyperthermia; as the nucleic acids , cell membrane and cytoskeleton within each cell is affected indirectly and/or through ...
