Approach to hand dermatitis in primary care.

Hand dermatitis is commonly seen in primary care, although it is often underdiagnosed. Exogenous causes should always be considered and a detailed environmental and occupational history taken, especially in patients presenting in adulthood. Although not life-threatening, the condition may have significant impact on the patient's quality of life and employment. Refractory cases or those suspected to be due to exogenous workplace agents may need to be referred for further investigation. Hand dermatitis can be treated effectively using pharmacotherapy and prevented by minimising subsequent exposure to irritants and allergens. Occupational skin disorders, once diagnosed, should be notified to the relevant authorities, i.e. the Ministry of Manpower in Singapore.
