Chronic Lymphocytic Leukemia: A Diagnostic Case Study
A clinical case of chronic lymphocytic leukemia (CLL) in a patient with significant leukocytosis, lymphocytosis, and lymphadenopathy. History, CBC, and ultrasound results are described.
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.
