Lung Cancer in Chronic Hypersensitivity Pneumonitis

Background: So far, the association of lung cancer with chronic hypersensitivity pneumonitis (CHP) has not been studied. Objective: We examined the prevalence and revealed clinical features of lung cancer in CHP. Methods: We retrospectively reviewed the medical records from 1994 through 2005 and identified 11 patients (15 lesions) with lung cancer among 104 patients with CHP. Their clinical fea...

Hypersensitivity pneumonitis

PURPOSE OF REVIEW To bring readers up to date on recent reports, both clinical and basic understanding, on hypersensitivity pneumonitis. RECENT FINDINGS Although many antigens and environmental settings have already been described as sources of this hyperimmune pulmonary disease, the literature continues to bring forth other conditions that can cause hypersensitivity pneumonitis. We also high...
