Mucinous adenocarcinoma is a type of cancer that arises from glandular epithelial cells and is characterized by the abundant production of mucin, a gelatinous substance. This cancer can occur in various organs, including the colon, rectum, breast, and ovary. The unique histological feature of this malignancy is the presence of extracellular mucin pools, which make up more than 50% of the tumor volume.
