Acute exacerbation of combined pulmonary fibrosis and emphysema associated with Hermansky–Pudlak syndrome

چکیده
A 30-year-old male smoker with congenital amblyopia and oculocutaneous albinism was admitted to our hospital complaining of progressive dyspnea on exertion. Chest computed tomography images revealed diffuse reticular opacities and honeycombing in the bilateral lower lobes with sparing of the subpleural region along with emphysema predominantly in the upper lobes. Lung biopsy specimens showed a mixture of usual interstitial pneumonia and a non-specific interstitial pneumonia pattern with emphysema. Of note, cuboidal epithelial cells with foamy cytoplasm on the alveolar walls and phagocytic macrophages with ceroid pigments in the fibrotic lesions were observed. The patient was diagnosed with Hermansky-Pudlak syndrome (HPS) associated with combined pulmonary fibrosis and emphysema (CPFE). Six years following the patient's initial admission to our hospital, he died from acute exacerbation (AE) of CPFE associated with HPS. This is one of only few reports available on the clinicopathological characteristics of AE in CPFE associated with HPS.

The clinical course and postmortem findings of a patient with pulmonary fibrosis which mimicked cryptogenic fibrosing alveolitis are reported. Histological examination revealed a chronic inflammatory infiltrate of pigment laden microphages.

متن کاملSurgery for secondary pneumothorax caused by Hermansky–Pudlak syndrome
Hermansky–Pudlak syndrome (HPS) is a rare, heterogeneously inherited, autosomal recessive group of disorders presenting with a triad of oculocutaneous albinism, a haemorrhagic defect secondary to platelet dysfunction and accumulation of ceroid-like material in the reticuloendothelial system [1, 2]. Although pulmonary fibrosis has occurred in a number of patients with this syndrome and generally...
متن کاملHermansky-Pudlak syndrome complicated by pulmonary fibrosis.
A 45-year-old woman from Puerto Rico presented to the emergency department with progressively worsening dyspnea over a 3to 4-day period. She had been diagnosed with type 1 Hermansky-Pudlak syndrome complicated by pulmonary fi brosis 4 years earlier. Previous renal biopsy demonstrated nephrosclerosis secondary to HermanskyPudlak syndrome. A brother also had Hermansky-Pudlak syndrome complicated ...
