A Study of Essential Hemoptysis

Long-term Outcome and Lung Cancer Incidence in Patients With Hemoptysis of Unknown Origin

“…In a study from 1952, 6 lung cancer developed in only 1 of 55 patients. In 1960, 7 none of 97 patients had lung cancer develop within 1 year. Lung cancer has become a disease of epidemic proportions since that time.…”

“…[1][2][3][4][5] In 1952, Douglass and Carr 6 used the term "idiopathic hemoptysis" to describe bleeding without an established cause after medical evaluation and bronchoscopy. In older studies, 6,7 it was suggested that the incidence of lung cancer in this population is low, and close follow-up has not been advocated. As lung cancer has become a disease of epidemic proportions in countries with a high incidence of tobacco use, we were interested to see if this remains the case.…”

Cryptogenic Hemoptysis

“…Dieulafoy disease of the bronchus may be involved in a subset of patients. dence of bronchial carcinoma complicating the course of cryptogenic hemoptysis, whereas older studies performed before the era of CT scanning suggested a favorable outcome (7)(8)(9).…”
