Case of the Week 330

This week's case was generously donated by Dr. LoAnn Peterson and Dr. Alicia Franken from Northwestern Memorial Hospital in Chicago.  The patient is a male in his early 50s with recent travel from Cameroon.  The following images are from Wright-Giemsa stained thin films made from peripheral blood.  Identification?

Plasmodium ovale....RBC fimbriation

Only ring forms, "applique" forms, "head phones" forms are present. Infected red cells are not larger than non infected red cells. Though some red cells are crenated, this should not be taken for fimbriation. There is no band forms observed. No other stages of development besides trophozoites are found.
All above clues are consistent with P. falciparum. This is a very heavy infection.
