Idiopathic Pulmonary Lymphoid Diffuse Hyperplasia

Abstract

We describe a 70 year old woman affected by diffuse pulmonary lymphoid hyperplasia (DPLH). DPLH is a rare clinical-pathological entity generally associated with connective tissue diseases, but we diagnosed our case as an idiopathic DPLH. To the best of our knowledge, this is the first case of idiopathic DPLH reported in medical literature.
