Hand and foot dermatitis




4: Hand and foot dermatitis


Abstract:



Rashes affecting the hands and feet are of great significance to the individuals affected by them because they affect activities of daily living in a way that is out of proportion to the amount of body surface area involved. As a result, these rashes frequently require more aggressive management than may be expected. This chapter discusses irritant contact dermatitis of the hands, allergic contact dermatitis of the hands, dyshidrotic eczema, and tinea pedis.

Key terms:


hand dermatitis


irritant contact dermatitis


allergic contact dermatitis


dyshidrotic eczema

palmoplantar psoriasis



Hand dermatitis—with a specific focus on irritant contact dermatitis, allergic contact dermatitis, and dyshidrotic eczema


Clinical features


Hand dermatitis is extremely common because the hands are exposed to many environmental chemicals and irritants.





Differential diagnosis


The differential diagnosis for hand dermatitis can be divided into true dermatitis (ICD, ACD, AD, dyshidrotic eczema, or nummular dermatitis) and other nondermatitic infection and inflammatory conditions, such as palmoplantar psoriasis, tinea manuum, and contact urticaria. As was previously mentioned, clinical examination alone is often insufficient for distinguishing the different types of true hand dermatitis from each other, with the exception of nummular dermatitis and dyshidrotic eczema, which have skin features that differentiate them from the other diagnoses.





Work-up


Hand dermatitis is typically a clinical diagnosis. All patients with hand dermatitis should have their nails and feet examined. A total-body skin examination for identification of rash elsewhere is also helpful.


History taking should be directed at assessing personal and occupational habits to identify potential irritants or allergens.
