Mucinous cystadenoma is a benign cystic tumor lined by a mucinous epithelium. It is a type of cystic adenoma ( cystadenoma ). Mucinous cystadenomas arise in a number of locations; however, cases of mucinous cystadenoma at different locations are not generally considered to be related to one another.
Pancreatic mucinous cystic neoplasm (MCN) is a type of cystic lesion that occurs in the pancreas. Amongst individuals undergoing surgical resection of a pancreatic cyst, about 23 percent were mucinous cystic neoplasms. These lesions are benign, though there is a high rate of progression to cancer. As such, surgery should be pursued when feasible.
A mucinous neoplasm (also called colloid neoplasm) is an abnormal and excessive growth of tissue with associated mucin (a fluid that sometimes resembles thyroid colloid). It arises from epithelial cells that line certain internal organs and skin, and produce mucin (the main component of mucus).
Cystadenocarcinoma is a malignant form of a cystadenoma and is a cancer derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness, and local extension and metastases occur.
Pancreatic mucinous cystadenoma is a tumour of pancreas. [1] It may be benign or be associated with an invasive carcinoma component. [1] Pathology. Microscopy.
A mucinous cystic neoplasm is an abnormal and excessive growth of tissue that typically has elements of mucin and one or more cysts. By location, they include: Pancreatic mucinous cystic neoplasm. These lesions are benign, though there is a high rate of progression to cancer. As such, surgery should be pursued when feasible.
Mucinous cystadenocarcinoma is a type of tumor in the cystadenocarcinoma grouping. It can occur in the breast [1] as well as in the ovary. [2] Tumors are normally multilocular with various smooth, thin walled cysts. Within the cysts is found a haemorrhagic or cellular debris. [2]
Mean age of presentation is at 45 years old. About 30% of biliary cystadenoma can progressively become malignant over time.
