Histoplasmosis, bone marrow aspirate, Wright stain This bone marrow aspirate is stained with the routine Wright's stain. It shows the intracellular Histoplasma yeast in the cytoplasm of a macrophage. Occasionally, Histoplasma can be found in the peripheral smear, in the cytoplasm of monocyte/macrophages, or even polymorphonuclear cells. Histoplasmosis is a common cause of anemia in AIDS patients from this area, where histoplasmosis is endemic.
