Dysplasia is a term used in Pathologyto refer to an abnormality in maturation of Cell_(biology) within a Tissue_(biology). This generally consists of an expansion of immature cells, with a corresponding decrease in the number and location of mature cells. Dysplasia is often indicative of an early Neoplasiaprocess. The term dysplasia is typically used when the cellular abnormality is restricted to the originating tissue, as in the case of an early, in-situ neoplasm.
