[Sarcoidosis at the Cochin University Hospital Center from 1975 to 1982]

An analysis of 80 cases of sarcoidosis admitted to the departments of respiratory medicine (36), rheumatology (19) and internal medicine (25) over a 7 year period, revealed a wide range of clinical presentations; there was a higher incidence of associated disease and a greater number of localisations of the disease in patients admitted to the department of internal medicine than in those admitted to the other two departments. On the other hand, bronchial biopsy was more commonly positive in patients admitted to the department of respiratory medicine whose respiratory function was more disturbed than the patients in the other two departments. The patients referred to the departments of rheumatology and internal medicine without radiological respiratory involvement had respiratory function tests and positive alveolar lavages. The prognosis was the same in all three departments; 50 p. 100 were treated with steroids. The recruitment of the patients in this series allows a different evaluation of the disease compared to series reported from more specialised departments.
