there is allergic and non-allergic

non-allergic is dose dependent and only at surface touched by the irritant

allergic type is delayed and manifests as a type IV hypersens.  no much irritant is needs because they skin is supersensitized

acute will have vesicles in clearly demarcated regions (soak with burow's solution, topical oral steroids)

plaques and mild erythema will show in sub-acute phase

chronic is characterized my mostly plaques which are lichtenized and there may be changes in pigmentation (test for allergies with patch test)

usually a chronic pruritic inflammation of skin, but can be acute

more common in males and usually self alleviates by mid-life

common in young, usually family history of hay-fever

"the itch that rashes"

coin-shaped plaques

AKA discoid eczema

4-5 cm in diameter

a vesicular type of hand/foor dermatitis

usually over 40 years age

starts with clear "tapioca" appearing clusters of vesicles, later turn into papules, then scales and lichenification

80% of it is on hands

spontaneous remission is often seen, but be on lookout for secondary infections
