An unusual cause of pulmonary fibrosis in a 71-year-old patient
A 71-year-old woman, suffering from spinal stenosis presented interstitial lung disease, albinism, and severe loss of visual acuity. On physical examination she showed tic-like automatism predominantly periorbital in the face and in the fingers. A computed tomography of the chest revealed typical findings of interstitial lung disease and additional mediastinal lymphomas and ground-glass attenuation in the lower regions of the lung. The findings of a transbronchial lung biopsy, presenting alveolar macrophages with ceroid-like material and platelet function studies proving slightly impaired platelet aggregation confirmed the clinical diagnosis of Hermansky-Pudlak syndrome. Sufficient pain control could be achieved without surgery and the patient was discharged home. 11 months after discharge, severe dyspnea and fever developed and finally the patient died of respiratory failure. The Hermansky-Pudlak syndrome is a rare cause of interstitial lung disease. In general, the lung disease presents in younger patients, but it may emerge in the elderly as well. Alveolar macrophages containing ceroid-like material are typical findings in BAL or lung biopsy. Furthermore impaired platelet aggregation and bleeding diathesis may be present. Both findings are useful to identify this rare disorder.
