Area of Science:

  • Pulmonary Medicine
  • Immunology

Background:

  • Hypersensitivity pneumonitis (HP) is an underdiagnosed interstitial lung disease.
  • It is characterized by pulmonary and systemic symptoms without extrapulmonary structural abnormalities.

Observation:

  • Clinical suspicion is paramount for diagnosing HP.
  • Diagnosis involves identifying causative inhaled antigens, excluding other lung conditions, and detecting antigen-specific antibodies.

Findings:

  • Two cases illustrate the diverse clinical, laboratory, and radiologic presentations of HP.
  • The variability in presentation can delay diagnosis.

Implications:

  • Emphasizes the need for increased clinical awareness of HP.
  • Highlights the importance of prompt diagnosis for successful treatment outcomes.
