Blasts in a Child's Blood Smear: Leukocytosis and Cytopenia
Clinical case of a 2-year-old child: leukocytosis 45.7×10⁹/L, anemia, thrombocytopenia. Differential diagnosis of blast cells in a blood smear.
Articles
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.
