Clinical cases
Cytological Features of Axillary Melanoma Cells
Cytological findings of confirmed axillary melanoma: polymorphic atypical cells, eccentric nuclei, prominent nucleoli, and pigment observed in the smear.
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.
