T-Cell Prolymphocytic Leukemia: Morphology and Phenotype
A clinical case of T-cell prolymphocytic leukemia: hyperleukocytosis 444×10⁹/L, cell morphology in blood smear, and characteristic immunophenotype.
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.
