Extramedullary Disease in Multiple Myeloma: Forms & Diagnosis
Explore the forms, pathogenesis, and diagnosis of extramedullary disease in multiple myeloma, including clonal migration mechanisms, imaging, and therapeutic approaches.
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.
