Informally, some experts have included these tumors as a distinct variant among a spectrum of mucus-producing adenocarcinomas, including — in order of increasing relative extent of cellular mucus production and extracellular mucus accumulation — solid adenocarcinoma, mucoepidermoid carcinoma, mucinous bronchioloalveolar carcinoma, signet ...
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 ).
Acinar adenocarcinoma of the lung is a highly lethal disease. Overall, the five-year survival rates approximate 16% to 22%. Generally, survival is better in all stages for patients with the acinar (or papillary) pattern than it is in patients with the solid pattern, but considerably worse than those with the bronchioloalveolar pattern.
The incidence of bronchiolo-alveolar carcinoma has been reported to vary from 4–24% of all lung cancer patients. [23] An analysis of Surveillance epidemiology and End results registry ( SEER) by Read et al. revealed that although the incidence of BAC has increased over the past two decade it still constitutes less than 4% of NSCLC in every ...
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.
