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.
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
Cystic lesions are found in 20.6% of all pancreatectomy specimens. Among this heterogeneous group, benign neoplasms predominate, particularly those with mucinous lining. Age at presentation, gender, location and tumor size are highly variable, with the exception of solid pseudopapillary tumor.
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.
Mean age of presentation is at 45 years old. About 30% of biliary cystadenoma can progressively become malignant over time. [1] Endometrioid cystadenoma (8380) Appendix: The term mucinous cystadenoma is an obsolete term for appendiceal mucinous neoplasm [2] The term "cystadenoma" may also refer to a hidrocystoma. [3]
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.
Mucinous cystadenocarcinoma of the lung (MCACL) is a very rare malignant mucus-producing neoplasm arising from the uncontrolled growth of transformed epithelial cells originating in lung tissue. Classification
