title: [Two cases of Hermansky-Pudlak syndrome with interstitial pneumonia].
abstract: Two cases of Hermansky-Pudlak syndrome with interstitial pneumonia were reported. Both patients had evidence of pulmonary involvement characterized by diffuse bilateral infiltrates. They had oculocutaneous albinism. Case 1 was a 55 year-old female who had a history of easy bruising. Her two sisters were albino and had died of pulmonary fibrosis. One of them was diagnosed as Hermansky-Pudlak syndrome on autopsy. Bone marrow aspirate disclosed typical macrophages with ceroid-like pigment. Transbronchial lung biopsy showed alveolar wall thickening. Lumi-aggregometer showed a decrease of platelet aggregation and an absence of ATP release. Case 2 was a 43 year-old female and had a bleeding tendency during a surgical procedure. Lumi-aggregometer showed normal platelet aggregation but an absence of ATP release. BALF analysis did not disclose macrophages with ceroid-like pigment.
