[Intense blood hyperosinophilia in Hymenolepis nana infestation. Considerations on 2 cases].

Two cases of infestation with Hymenolepis nana are reported in which evidence was found of intense blood hypereosinophilia (in average 50%); this is not in keeping with the classical data on parasitic hyperosinophilia, thus confirming the strictly individual character of the eosinophilic reactions in parasitoses, as also sustained by other authors.
