Acute Myeloid Leukemia Diagnosis: A Clinical Case Study
A clinical case of acute myeloid leukemia (AML M2) featuring blastemia, hyperleukocytosis, blood smear morphology, and bone marrow immunophenotyping and PCR results.
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.
