Acute Lymphoblastic Leukemia: Morphology and Cytochemistry
A clinical case of acute lymphoblastic leukemia in a 21-year-old patient: blast morphology in blood and bone marrow, MPO, PAS, and lipid cytochemistry results.
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.
