(biology) A reversion of differentiation in cells that is characteristic of malignancy in tumours.
Anaplasianoun
loss of structural differentiation within a cell or group of cells often with increased capacity for multiplication, as in a malignant tumor.

Anaplasia
Anaplasia (from Ancient Greek: ἀνά ana, + πλάσις plasis, ) is a condition of cells with poor cellular differentiation, losing the morphological characteristics of mature cells and their orientation with respect to each other and to endothelial cells. The term also refers to a group of morphological changes in a cell (nuclear pleomorphism, altered nuclear-cytoplasmic ratio, presence of nucleoli, high proliferation index) that point to a possible malignant transformation.Such loss of structural differentiation is especially seen in most, but not all, malignant neoplasms.
Dysplasianoun
(pathology) Abnormal development of cells or tissue, often a precancerous stage of growth.
Dysplasianoun
abnormal development (of organs or cells) or an abnormal structure resulting from such growth
Dysplasia
Dysplasia is any of various types of abnormal growth or development of cells (microscopic scale) and/or organs (macroscopic scale), and/or the abnormal histology or anatomical structure presumably resulting from such growth. Dysplasias on a mainly microscopic scale include epithelial dysplasia and fibrous dysplasia of bone.
