The occurrence of sarcoidosis in more than one member in the same family is a fact that has been noted by many authors. It is now recognized as Familial Sarcoidosis, and nearly 450 cases have been reported in the world literature. Included in this figure are consaguineal cases as well as contacts without genetic relationship. The incidence of Familial Sarcoidosis (FS) is in striking contrast in the different series of recorded sarcoidosis cases. While some authors indicate 12% of the sarcoidosis total, others refer to up to 44.7% with an average of 7% in the literature. We report a new case of Familial Sarcoidosis that according to our knowledge of the literature is the first case referred to from Spain.
