Abstract
Diagnostic cytology is a branch of pathology that attempts to diagnose human diseases, mainly cancer or precancerous states of various organs, by microscopic examination of cell samples, rather than tissue biopsies [1],[2]. There are several methods of obtaining cell samples. The cells may be secured by scraping or brushing the surface of the target organs (such as the uterine cervix, the oesophagus or the bronchus, to name a few). Cells may also be obtained by means of a needle-syringe system that may be used for aspiration of fluids accumulated in a body cavity or deeply seated lesions. Cells of diagnostic value may also be contained in urinary sediment or sputum. Regardless of origin and type of procedure, the sample is usually examined in the form of smears or equivalent preparations that must be stained to enhance the diagnostic features of cells. This is not the place to describe in detail the microscopic features that are of diagnostic significance and the interested reader is referred to other sources [1],[2]. Suffice to say, that the differences between benign and malignant cells are reflected mainly in the configuration and staining qualities of the nucleus of the cells, a small structure measuring from 7 to 12 microns in diameter.
