Palisade (pathology)
Palisade (pronunciation: /ˈpalɪseɪd/), in the field of pathology, refers to a characteristic arrangement of cells, typically seen in certain types of tumors and skin diseases. The term is derived from the French word palissade, meaning a fence or barrier, due to the resemblance of the cellular arrangement to a row of fence posts.
Etymology
The term palisade is derived from the French palissade, which in turn comes from the Latin palus, meaning stake. This is in reference to the characteristic appearance of cells in a palisade arrangement, which resemble a row of stakes or fence posts.
