This term is also understood to be reversible changes in cells, tissues and organs which are characterized on the one hand by atypical growth processes and loss of differentiation . The transitions to anaplasia are fluid. On the other hand, aplasia is also to be regarded as dysplasia, which, however, in contrast to agenesis, is characterized by the non-development of an organ despite the presence of an organ.
When looking at the fine tissue structure of an organ, the term dysplasia is understood to mean a deviation of the tissue structure from the normal picture. If dysplasias appear more frequently in the microscopic examination results of a histological examination , these can be precancerous stages .
