Adequate cell blocks allow for additional studies and can provide a specific diagnosis and information essential for targeted treatment plans. They can be particularly useful for categorization of tumors that otherwise may not be possible from smears themselves. This improved preparation offers excellent cytomorphologic features corresponding closely to cells in Papanicolaou-stained smears and ensures optimal preservation of histochemical and immunocytochemical properties. The technique is simple and reproducible and uses routine safe laboratory chemicals. Gupta V, Shukla S, Husain N, Kant S, Garg R. J Cytol.
