Case of the Week 396

This week's case is a peripheral blood smear from a 52 year-old businessman from India. Identification?

They look like the trophozoite form of Plasmodium vivax because of the amoeboid cytoplasm with Schuffner's dots.

The infected red cells are larger than the ones not infected denotes a predilection for younger red cells or reticulocytes. The shying away from the adjacent one had been pointed out in a previous case by Dr. Pritt as a soft characteristic of such vivacious trophozoites.Though the last picture does show some fimbriation, given the geographic location being India, my vote will go for Plasmodium Vivax.

Large red blood cells; large irregular rings, Schuffner's dots, and ameboid trophozoites, so yes, this is a characteristic blood smear of Plasmodium vivax malaria. Now that been said, knowing that case was reported from India we cannot rule out that similar blood smears have been seen in Plasmodium ovale curtisi and P. ovale wallikeri. Regardless, the most likely diagnosis should be P. vivax without much doubt.
