Classification of disease acronym

Autoimmune
3 broad types of structural change
Increased, decreased, or altered cellular activity
Hypertrophy
Increase in the size of tissue or organ due to increased size* of the individual cells
Hyperplasia
Increase in the size of tissue or organ due to an increase in the number* of cells
Atrophy
Decrease in the size of tissue or organ due to a decrease in the number and/or size of cells
Metaplasia
Change of one cell type into another
It is reversible
May progress to dysplasia if continued exposure to noxious stimulus
Dystrophic calcification
Deposition of calcium in damaged tissue
