Sarcoidosis is a systemic disease of undetermined etiology although it can be related to genetic or environmental factors or both. We investigated 19 polish caucasian families with at least two affected relatives and healthy families members in order to evaluate the clinical aspects of familial sarcoidosis and the influence of environmental factors. We have found three types of familial sarcoidosis: 10 sib pairs, 1 sib triplet, 5 parent offspring pairs and one case of sarcoidosis in cousins.

Although very little is known about the aetiology of sarcoidosis, its immunopathogenesis is now better known. The interaction of alveolar macrophages and T cells may play a role in the pathomechanism of the disease. To infiltrate the tissue, lymphocytes have to migrate through the subendothelial basement membrane and interstitium, rich in extracellular matrix (ECM).
