IPF is primarily characterized by the UIP pattern, but histological examination may also identify other patterns associated with different interstitial lung diseases, such as:
- Nonspecific Interstitial Pneumonia (NSIP): More uniform inflammation and fibrosis without honeycombing. - Desquamative Interstitial Pneumonia (DIP): Presence of numerous macrophages within the alveoli.
It is essential to distinguish UIP from these patterns for accurate diagnosis and management.
