Hermansky-Pudlak Syndrome Type 1 Presenting with Interstitial Lung Disease: A Report of a Rare Case from Saudi Arabia.

BACKGROUND Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder characterized by oculocutaneous albinism, bleeding diathesis, and potential multi-organ involvement such as pulmonary fibrosis and granulomatous colitis. While its incidence is globally low, it may be under-reported, particularly in regions with high rates of consanguinity, such as the Middle East. By reporting this case, we aim to increase awareness of this condition as well as its association with ILD.
