Thrombocytopenic purpura in infectious mononucleosis-- A rare complication?

We have presented an illustrative case of thrombocytopenic purpura complicating infectious mononucleosis. Steroid therapy appeared to be beneficial although spontaneous recovery cannot be excluded. The use of the Paul-Bunnell heterophil agglutination test is recommended for patients having idiopathic thrombocytopenic purpura to rule out subclinical infectious mononucleosis. It is suggested that this syndrome be treated with the expectancy of long-term remissions. Steroids appear to be of benefit. Platelet recovery is usually complete in less than 60 days. Splenectomy should not be considered until at least two months have passed. Chronic thrombocytopenia is an unlikely complication.
