A rare diagnosis: Hermansky-Pudlak syndrome in a patient with pulmonary fibrosis, oculocutaneous albinism and thrombocytopathy

Hermansky-Pudlak Syndrome (HPS) is an autosomal recessive disorder associated with oculocutaneous albinism, bleeding diathesis, granulomatous colitis, and highly penetrant pulmonary fibrosis in some subtypes. Homozygous or compound heterozygous mutations in HPS1, HPS3, HPS4 and several other genes lead to clinical manifestation of the disease.
