Here are two words that can cause some serious headaches for pathology students: differentiation and dysplasia. Both terms are graded on a scale. Cells can be anywhere from well-differentiated (pretty normal looking, and resembling the cells from which they originated) all the way down to poorly differentiated (“bad” looking, and not really resembling the cells from which they originated at all). Similarly, dysplasia is graded on a mild – moderate – severe scale.
