Clubbing of the Fiingers: Bulbous appearance of the distal fingers associated with a number of uncommon lung conditions (e.g., cystic fibrosis, IPF, cancer, etc.). Note the loss of the diamond-shaped window that appears between the two fingers when cuticle areas are placed next to each other (picture on far right is normal for comparison).
