Burn
Extent of burn injury us determined by amount of surface area damaged (TBSA total body surface area) and depth of damage. Is life threatening when:
large TBSA is damaged and exposed skin to infection
classification if a burn or injury by depth if skin:
partial thickness (superficial)
partial thickness (deep)
full thickness (to subcutaneous layer)
skin infection. Cluster if furuncles or boils. common source of infection is staphylococci bacteria/latin carbo (live coal refers to hot pain)

basal cell (less dangerous/more common)
squamous cell (can be dangerous)
inflammation of lil cells. Inflammation of the connective tissue in the dermis. Caused by infection that spreads from the skin surface or hair follicles to the dermis, and sometimes subcutaneous tissue.
cellulitis
cellul - lil cell
itis- inflammation

urticaria
hives
vesicles
blisters
wheals
itchy elevation of skin
types of dermatitis:
contact-physical contact with triggering substance
