Which term denotes disorganization or abnormal arrangement of cells?

The term that denotes disorganization or abnormal arrangement of cells is dysplasia. Dysplasia is a term often used in pathology to describe an abnormal development or growth of tissues or organs, which can include changes in the size, shape, and organization of cells. It typically indicates that the cells are not in their normal arrangement and might be a precursor to cancer, making it critical for diagnostic purposes in medical practice.

Anaplasia refers to a more severe degree of cellular abnormality typically associated with cancerous tissues, where cells lose their differentiation and appear undifferentiated. Hypoplasia denotes incomplete development or underdevelopment of tissues or organs, which is different from abnormal arrangement. Hyperplasia describes an increase in the number of cells, leading to swelling or enlargement of a tissue or organ, but does not involve disorganization of cells.
