A mucinous adenocarcinoma is a type of cancer that produces what is called “mucin”, which is the main component of mucus. They begin to form on the lining of certain internal and external organs like the skin. Mucinous adenocarcinoma’s from cells called “epithelial cells”. On the skin, it can be recognized by its characteristic reddish, elevated mass that is often round and ulcerated.
“Adeno-“ means “gland”. Glands commonly secrete things in the body (endocrine glands) or outside of the body (exocrine glands). For example, mucous and sweat are secreted by exocrine glands.
A “Carcinoma” is a malignant tumor that starts in epithelial cells. If you put the 2 words together (Adeno-Carcinoma) you will see that what they mean are malignant tumors that start in the epithelial cells lining endocrine or exocrine glands.
Now to the term “mucinous”. Mucinous simply means “lots of mucous”.
So to bring it all together, a Mucinous Adencarcinoma is a malignant tumor that originates in epithelial cells on exocrine glands with lots of mucous.
It has been suggested by experts that the presence of mucouse can help a cancer spread faster through the body. This means that mucinous adencarcinoma’s are considered quite aggressive cancers then regular adencarcinomas and so are also harder to treat.
Mucino adenocarcinoma account for 10-15% of all adenocarcinomas.
