Adenocarcinoma of the lung is the most common type of lung cancer, and like other forms of lung cancer, it is characterized by distinct cellular and molecular features. [1] It is classified as one of several non-small cell lung cancers (NSCLC), to distinguish it from small cell lung cancer which has a different behavior and prognosis.
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.
Nearly 40% of lung cancers are adenocarcinomas, which usually originates in peripheral lung tissue. [10] Most cases of adenocarcinoma are associated with smoking; however, among people who have smoked fewer than 100 cigarettes in their lifetimes ("never-smokers"), [11] adenocarcinoma is the most common form of lung cancer.

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 ...
The majority of cancers of unknown primary, about 90%, are adenocarcinomas, with 60% appearing as moderately to well-differentiated adenocarcinoma, while about 30% are poorly differentiated adenocarcinoma. The term adenocarcinoma refers to cancer that begins in the cells in glandular structures in the lining or covering of certain organs in the ...
There also seems to be an association with clear cell lung cancer variants. [13] A case of combined small cell lung carcinoma featuring components of FA and cells resembling those from carcinoid tumor has been reported, illustrating the unique complexity and heterogeneity of divergent histogenesis and cell differentiation in lung cancer. [14]
Atypical adenomatous hyperplasia is a subtype of pneumocytic hyperplasia in the lung. It can be a precursor lesion of in situ adenocarcinoma of the lung (bronchioloalveolar carcinoma). In prostate tissue biopsy, it can be confused for adenocarcinoma of the prostate. The needle biopsy rate is less than 1%.
