  • Pulmonary Eosinophilia

    a condition characterized by infiltration of the lung with eosinophils due to inflammation or other disease processes. major eosinophilic lung diseases are the eosinophilic pneumonias caused by infections, allergens, or toxic agents.

  • Eosinophils

    granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin.

Patient EducationClinical

Eosinophilic Disorders

Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body's immune response. They can also build up and cause inflammation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
