Leukemoid reaction induced by prenatal administration of betamethasone

Abstract

A case of leukemoid reaction in a premature baby whose mother was antenatally treated by betamethasone is reported. The neonatal and maternal factors which might lead to leukocytosis or leukemoid reaction were excluded. The presented case is the last in a series of eight previously reported cases of leukemoid reaction, in which the common denominator was the antenatal administration of betamethasone.
