The 2025 International Classification of Interstitial Pneumonias: What’s New?

The 2025 ERS/ATS Statement is here, and it’s changing how we classify interstitial pneumonias. From the introduction of BIP (Bronchiolocentric Interstitial Pneumonia) as a major pattern to the unified approach for idiopathic and secondary causes, this update is a game-changer for clinical practice.  Key Takeaways: • BIP is now a major pattern.  • Unified classification for idiopathic AND secondary causes.  • New terminology: Alveolar Macrophage Pneumonia (AMP) replaces DIP.  • Emphasis on diagnostic confidence in clinical management.
