Infected red cells larger than non infected RBCs, a predilection for reticulocytes. Schuffner dots presents. Geographic detail and all other clues points toward P. vivax.

This was a case of malaria caused by Plasmodium vivax. Diagnostic morphologic features included:Amoeboid trophozoites with sturdy chromatin in enlarged red blood cells containing Sch├╝ffner's. Polygonal shape typical of P. vivax.

Vivax, for all of the above reasons, plus the edges take on the shape of the cell next to it (Learned that here LOL)
