WE WISH to add 2 cases of histoplasmosis in infancy to the gradually enlarging list of cases of this disease in children and adults being reported.

Furthermore, it has some symptoms which belong to certain other diseases of childhood from which it must be differentiated, among them, leukemia and tuberculosis.
