Abstract
Cytology is the diagnostic branch of medicine which, based on the microscopic cell examination, to recognise physiological conditions, and to diagnose benign, pre-malignant and malignant processes. It is easy, inexpensive, fast, reliable, and gives material for ancillary testing. Almost all surgeries for lung, pancreas, liver, thyroid, etc. are based on cytology diagnoses. Almost all biopsies of Cervix, bladder, etc. are done based on cytology diagnoses. However, cytology is different and difficult, due to potential subjectivity, heterogeneity and nonuniformity of material. Cytopathology studies diseases on the cellular level while in histopathology; cells are assessed in the spatial context. So cytology has different knowhow and diagnostic approach compared to histopathology. This presentation demonstrate diagnostic approach and general cytomorphology features (patterns, background, cell type, shape, cytoplasmic features,…..ect) in cytology material and potential diagnostic pitfalls and errors. High diagnostic accuracy and avoidance of cytologic pitfalls in cytopathology can be achieved by acquiring a detailed clinico-radiologic data, obtaining adequate specimens, having prior knowledge of the variety of diagnostic entities, strict application of established cytological criteria, and nothing can replace years of experience.
