[Neonatal Caffey-Silverman disease with thrombocytosis, increase in C-reactive protein and immunoglobulins].

An unusual case of Caffey-Silverman's disease with thrombocythemia and increased type M immunoglobulins and C-reactive protein levels is reported. These particularities were rarely reported in the literature. These conditions suggest that control should be exercised before steroid treatment in view of the known thrombocythemic effect of the drug. These hematologic abnormalities suggest that this syndrome is infectious in origin and emphasize the risk of steroid treatment.
