Berezovsky-Sternberg Cells in Hodgkin's Disease
Morphology of Berezovsky-Sternberg cells and Hodgkin cells in cytological preparations of lymph nodes in Hodgkin's lymphoma. Features and microscopy.
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.
