The diagnosis of sarcoidosis was established in a 6-year-old boy and his mother. We made a review of other familial cases of sarcoidosis and compared them with the sporadic form of the disease. There are no data to support a separate nosologic identity for the familial illness, although there seems to be a similar pattern of involvement in members of a given family.
