Introduction
There are many causes of blistering and peeling on the hands. A relatively common cause is allergic contact dermatitis, which typically occurs after exposure to substances to which an individual is sensitive, leading to localized blistering and peeling. Another common cause is dyshidrotic eczema (pompholyx), often associated with excessive hand sweating; this condition can also manifest as localized blisters and scaling.
There are many causes of blistering and peeling on the hands. A relatively common cause is allergic contact dermatitis, which typically occurs after exposure to substances to which the individual is sensitized, resulting in localized blistering and desquamation. Another common cause is dyshidrotic eczema (also known as pompholyx), often associated with excessive hand sweating, presenting clinically with localized blisters and scaling. Some patients may have keratolysis exfoliativa, which also manifests as scaling.
Fungal infection is another possible cause; affected individuals may present with scaling and localized blisters. Therefore, to determine the precise underlying cause, an in-person consultation at a hospital is essential. Following clinical evaluation, the physician will decide on appropriate diagnostic tests—for instance, in suspected fungal infection, potassium hydroxide (KOH) microscopy or fungal culture may be performed. Antifungal therapy would be indicated if a fungal infection is confirmed, whereas allergic causes—as previously mentioned—would be managed with antiallergic treatment.
