The rashes were associated with increased serum gammaglobulin G levels and rather severe lung disease. The rashes are probably the expression of chronic lung infection and high antigenic load in these patients. Their appearance was associated, in most cases, with poor long-term survival.(AJDC. 1989;143:1030-1032)
