Variegation (histology)
Variegation (histology)
Variegation (pronunciation: /ˌvɛərɪˈɡeɪʃən/) in histology refers to the appearance of different colors or shades in a tissue sample, often seen in pathological conditions. The term is derived from the Latin variegatus, meaning 'diversified', 'varied'.
Overview
In histology, variegation is often indicative of a disease process. It can be seen in various conditions such as cancer, inflammation, and infection. The variegated appearance is due to the presence of different types of cells or substances within the tissue. For example, in a cancerous tumor, the variegation may be due to the presence of both normal and cancerous cells. Similarly, in an inflamed tissue, the variegation may be due to the presence of inflammatory cells and damaged tissue.
