Definition

Cytology is the microscopic examination of cells, isolated or in small clusters, spread on a glass slide and stained to distinguish more easily their apect, their origin and anomalies to obtain a cytodiagnosis. It has the advantage of showing the cellular details and the disadvantage of not providing any indication of the tissue organization, architectural anomalies and areas of flooding.
Cytology based on the knowledge of morphological characteristics of normal or pathological cells isolated from their tissue context: the size and shape of cells, their grouping mode, and the type of intercellular substances. It allows to detect the presence of normal cells but can not determine if a cancer is invasive or not.
Having no forensic value, especially a value of diagnostic orientation.
