Mucinous adenocarcinoma

Mucinous carcinoma is a type of cancer that arises from epithelial cells; these line certain internal organs and skin, and produce mucin (the main component of mucus). Over 40 percent of all mucinous carcinomas are colorectal.When found within the skin, mucinous carcinoma is commonly a round, elevated, reddish, and sometimes ulcerated mass, usually located on the head and neck.
