Introduction:
Idiopathic chronic eosinophilic pneumonia (ICEP) or Carrington's disease is an infiltration of the lung parenchyma by eosinophils without known cause. The diagnosis of ICEP is based on well defined clinical and radiological characteristics associated with blood and/or alveolar eosinophilia. Alveolar hypereosinophilia is marked and regarded as a constant feature.
Case Report:
We report the case of a 57 year old man seen on account of a cough and deterioration of general health associated with radiographic peripheral pulmonary infiltrates, blood hypereosinophilia but no hypereosinophilia in the bronchial lavage (BL). The diagnosis of ICEP was made after histological examination of a surgical lung biopsy.
Conclusion:
Absence of alveolar hypereosinophilia in ICEP remains exceptional and in this case confirmation of the diagnosis may depend on examination of a lung biopsy.

This is the first step in diagnosing and managing asthma. It includes:
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
