Flashcards
Neoplasia
Neoplasia
The formation of a new, abnormal mass of cells that can grow out of control.
Anaplasia
Anaplasia
A lack of differentiation in cancer cells, meaning they lose their specialized characteristics and appear primitive.
Hyperplasia
Hyperplasia
An increase in the number of cells within an organ or tissue, often in response to a specific stimulus.

Study Notes
Neoplasia
- Abnormal mass formed from proliferating cells
- Cells have significant independence (autonomy)
- Formation of an abnormal mass of proliferating cells, possessing a significant degree of autonomy
Anaplasia
- Lack of cell differentiation in neoplasms
- Cells appear as a mass of primitive, varying-shaped (pleomorphic) cells
- Lack of differentiation in neoplastic cells; seen as a mass of pleomorphic primitive cells
Hyperplasia
- Cellular response to a stimulus
- Increased cell proliferation within an organ/tissue
- Can lead to organ enlargement or benign tumor formation
- Cell response to a specific stimulus, the proliferation of cells within an organ or tissue beyond normal; may result in the gross enlargement of an organ, the formation of a benign tumour.
Metaplasia
- One mature cell type transforms into another mature cell type
- One differentiated cell type changes into another mature differentiated cell type
Dysplasia
- Abnormal development
- Alterations in adult cell size, shape, and organization
- Abnormality of development, alteration in size, shape and organization of adult cells
