Epithelial Sheets and Mucus in Urine Sediment: Preparation Errors
How patient preparation defects affect urine sediment microscopy. Massive accumulations of squamous epithelium and mucus hindering cell differentiation.
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.
