Cerebral malaria in a young woman who had traveled to Africa

A young woman became sick after visiting Zambia. She died a few weeks after onset of headache and flu-like symptoms. The slide is not dirty! The dirty-looking stuff in the picture below is birefringent pigment called hemozoin. This is typical of a falciparum infection. There are ring hemorrhages and Dürck granulomas present as well. Dürck granulomas are accumulations of mononuclear cells, predominantly macrophages, probably related to resorption of ring hemorrhages.
