UIP (Usual Interstitial Pneumonia)

Usual Interstitial Pneumonia (UIP) is a pattern of lung tissue damage characterized by progressive scarring (fibrosis) mainly in the small air sacs and tissue support structures. This scarring thickens the lungs, making it harder for oxygen to pass into the blood. UIP is commonly associated with idiopathic pulmonary fibrosis (IPF), a chronic, progressive lung disease. It presents with symptoms like shortness of breath and a dry cough. On imaging and lung biopsy, UIP shows characteristic patterns of uneven fibrosis and honeycombing (cystic spaces). The condition is progressive and currently has no cure, but managing symptoms and slowing progression are key goals.
