Hermansky-Pudlak Syndrome: A Rare Congenital Disorder With Interstitial Lung Disease.

Hermansky-Pudlak syndrome (HPS) is a genetic multisystemic disorder with oculocutaneous albinism, granulomatous colitis, bleeding diathesis, and pulmonary fibrosis. Multiple subtypes of HPS exist, with certain types having higher predilection for pulmonary fibrosis. This case report focuses on the demonstration of pulmonary imaging findings seen in a patient. Several imaging features overlap with idiopathic pulmonary fibrosis including traction bronchiectasis, pleural and peribronchovascular thickening, and reticulations. This case report highlights the differences seen in lung disease associated with HPS compared to other interstitial lung diseases, in addition to the multi-systemic features of HPS.
