SARCOIDOSIS IN EUROPE: A COOPERATIVE STUDY

: The data on the epidemiologic situation of sarcoidosis from 24 countries of Europe have been reviewed. The new facts seem to demonstrate that the differences between the frequency of this disease in the north and south are not real. The actual situation is dependent on the general knowledge of this disease and on the extent and intensity of the active detection of its asymptomatic stage. A new prospective cooperative study of the yearly incidence of all forms of sarcoidosis in the total population of at least some European countries would be desirable.
