Mucinous adenocarcinoma of the appendix is a type of cancer that starts in the gland-forming cells that line the appendix. These cancer cells produce large amounts of mucin, a thick, jelly-like material. Unlike low-grade mucinous neoplasms (LAMNs) and high-grade mucinous neoplasms (HAMNs), mucinous adenocarcinoma shows destructive invasion, meaning the tumor grows aggressively into the wall …

Invasive mucinous carcinoma is a distinct subtype of breast cancer in which the tumor cells are surrounded by large amounts of a gel-like substance called mucin. To be classified as mucinous carcinoma, at least 90% of the tumor must consist of mucin-containing tissue. Compared to the more common invasive ductal carcinoma, invasive mucinous carcinoma tends …

Mucin is normally produced in small amounts by the cells lining the inside of the colon, but in mucinous adenocarcinoma, cancer cells produce it in large quantities. …

Mucinous carcinoma of the ovary is a type of ovarian cancer that develops from cells that produce mucus. Under the microscope, the tumor cells resemble the cells that line parts of the digestive tract, such as the stomach or intestines, which is why pathologists describe this tumor as having “mucinous” or gastrointestinal-type features. Mucinous carcinoma …
