[Neonatal hemolysis secondary to congenital poikilocytosis]

Hereditary pyropoikilocytosis is a congenital haemolytic anaemia recently described. A new case is reported in which the condition was diagnosed by a study of erythrocyte membrane proteins in the parents. The unusual clinical features of this case lead to a discussion of the relationship between hereditary pyropoikilocytosis and other rare forms of elliptocytosis in children.
