What is pathology?
Study of tissues under abnormal conditions, the nature of a disease and its causes, development and consequences.
Pathology addresses what 4 components of disease?

Category/classification: What is a serum filled papule or plaque?
Wheal (hives)
Category/classification: What is a lesion characterized by the surface epithelium and frequently some of the underlying connective tissue? Often appears depressed or excavated.
Ulcer
Category/classification: What is a superficial lesion, often raisin secondary to rupture of a vesicle or bulla, that is characterized by partial or total loss of the surface epithelium?
Erosion
Category/classification: What is a shallow linear crack in the epidermis often associated with hypersalivation, xerostomia, and dehydration?
Fissure
Category/classification: What is the thinning of tissue layers, decrease in size of cells/loss of tissue?
Atrophy

Crater
Surface texture: What is a hard covering, composed of dried serum, pus, blood, or combination?
Crust
Surface texture: What is hardness of tissue from increased number of surrounding epithelial cells?
