Acute eosinophilic pneumonia caused by cigarette smoking

It has Been suggested that acute eosinophilic pneumonia (AEP) is associated with cigarette smoking because in Japan, the patients with AEP are young a nd have a high incidence of short-term smoking history. However, there: has been no direct evidence to support that cigarette smoke causes AEP, Herein is reported the first case showing the direct evidence and a long-term cli nical course of cigarette smoking-induced AEP, in which tolerance to repeat ed assumption of smoking cigarettes might have occurred. We should pay atte ntion to the history of cigarette smoking in seeing patients with AEP, espe cially in young patients.
