Bone Marrow Morphology in Severe Hypereosinophilia
A clinical case of hypereosinophilia: morphology of eosinophilic lineage cells in bone marrow, signs of degranulation, and differential diagnosis with MPN.
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.
