[Neutropenia in infancy - sometimes chronic and benign - own experiences].
Chronic neutropenia is a decrease in circulating neutrophils in the peripheral blood lasting over 6 months. Values need to be refered with the age and race. In children aged 2 weeks to 12 months reffered values are above 1000/03BCL. There are congenital and aquired reasons of neutropenia in infancy. The most common type of chronic neutropenia in infants is chronic, benign neutropenia (AIN). Authors present ten infants between three and six months with chronic, benign neutropenia. The reason of ordering laboratory tests at outpatient clinic were benign upper respiratory tract infections (four cases), pallor (four cases) and on parental demand (one case). In one infant neutropenia was observed during treatment of pneumonia at a district hospital.
