- The rash begins shortly after exposure to the irritant; localized to the exposure areas (below = poison ivy)
- Hypersensitivity reactions in skin can cause allergic reactions due to cutaneous contact or ingestion of allergens, such as drugs
- These reactions are caused by mast cell degranulation or lymphocyte activity
- Symptoms may include pruritus and erythematous rash with distinct patterns in contact dermatitis or poorly defined areas in food or drug reactions
- Diagnosis can be aided by a history of drug ingestion, contact with allergens, or previous reactions
- Treatment options include stopping exposure to the offending agent, using topical corticosteroids and antihistamines for mild cases, and using oral corticosteroids for more severe cases
