The relationship between IP activity and psoriasis activity in case 6, a 72-year-old man.7 Interstitial pneumonia activity was evaluated by chest CT and serum KL-6, and psoriasis activity was assessed by PASI scores. Chest CT showed subpleural ground-glass and irregular linear (reticular) opacity distributed in the lower lobes. Interstitial pneumonia activities fluctuated in accordance with psoriasis activity.
