Abstract
Contact dermatitis (CD) is usually the result of cumulative exposure to sensitive irritants and accounts for 80% of all contact dermatitis cases. ICD can coexist with atopic dermatitis (AD) and allergic contact dermatitis (ACD). Patients with Alzheimer's disease and ACD may also have a lower infection threshold for ICD. Therefore, it must stand out from EA and CAD lesions. People with ICD have experienced uncontrolled tingling and burning sensations. Itching is typically manifested in patients with AD and ACD. Compared with AD and ACD, ICD lesions are usually well described. The prognosis of ICD is based on the exclusion method. Monitor patients to rule out type 1 and type 4 hypersensitivity reactions. A negative result indicates the prognosis of ICD. Management includes identifying and avoiding irritants through the normal use of emollients. Although ICD is older, it is not uncommon in some majors, and genetics and environment play a vital role in its development.
