Familial thrombocytosis in infancy presenting with a leukaemoid reaction.
Familial thrombocytosis (FT) is a hereditary disorder probably involving the regulation of megakaryopoiesis. This report is the first documented case of FT in infancy. The clinical course was complicated by a leukaemoid reaction which lasted for several months, in combination with failure to thrive and hepatosplenomegaly. At the age of 5 years the patient, with the exception of thrombocytosis, is healthy and without medication.
