Severe Poikilocytosis and Schistocytes in Blood Smear
A case of severe poikilocytosis in an ICU patient: schistocytes, normoblasts, and erythrocyte fragmentation (dumbbell and rod shapes) in a blood smear.
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
