Clinical cytology is an interdisciplinary diagnostic field of medicine that performs microscopic analyses of cells of various biological specimen in order to recognize physiological states, as well as detecting and diagnosing benign, premalignant and malignant pathological processes. Spontaneously desquamated epithelium or material obtained by fine-needle aspiration (FNA) of organs, masses and bone marrow are common materials used for cytological analysis. FNA can be done “blindly” for palpable masses, or under the control of some visualization methods, which is the method of choice, especially if it is done by the cytologist who also analyzes the slides. While interpretating cytological reports, the most important thing is the morphological analysis of specimen which contributes to detecting the correct diagnosis alongside the clinical information. In certain cases additional methods such as cytochemistry, immunocytochemistry, immunophenotipization and cytogentics are used. Based on the above mentioned, the cytopathologists come to a conclusion that has to be clear, concise, clinically relevant and must use clear nomenclature understood by clinicians in the same or different institution.
