In pathology, cells are described as plasmacytoid if they are round and if the nucleus (the part of the cell that holds the genetic material) is located to the side of the side. Pathologists often describe the location of the nucleus as eccentric or peripheral. These cells are described as plasmacytoid because they look like …

E-cadherin is a protein normally found on the surface of epithelial cells. Epithelial cells line the surfaces inside and outside of your body, including your skin, digestive tract, and various organs. E-cadherin helps epithelial cells stick tightly to each other, maintaining the structure and integrity of tissues. Why do pathologists test for E-cadherin? Pathologists test …
