Dyshidrotic eczema | Eczema between the toes

Dyshidrotic eczema

Dyshidrotic eczema is a skin change that can occur mainly on the hands and feet. In the past, it was thought that the cause of this eczema was a disorder of the sweat glands, hence the name (Hidrosis refers to the formation of sweat, so dyshidrosis is a disturbed formation of sweat). Nowadays, however, it is known that eczema is caused by allergic, toxic or atopic (e.g. in the context of neurodermatitis) causes and that the increased sweat production is more likely to be a symptom.

Dyshidrotic eczema is characterized by reddened skin with numerous bulging blisters filled with clear to slightly yellowish fluid. The skin is sensitive and usually itches severely. It can also lead to an additional infection with bacteria and fungi, which aggravate the clinical picture.

The diagnosis of dyshidrotic eczema is mainly made by a clinical examination, additionally a test for allergies and atopy can be performed. Therapeutically, light forms can be treated with cortisone-containing ointments and local UV-A rays. For severe forms, systemic steroids in the form of tablets may be necessary.

Eczema or skin fungus

The differentiation of skin fungus and eczema is usually not easy, but there are some features that can help in differentiation. Both diseases have in common that the affected skin between the toes is often very sensitive and hurts and itches when touched lightly. Small skin tears are also possible in both diseases.

Eczema usually manifests itself with a reddening of the skin, and in the case of infestation with skin fungi, a rather grayish-white scaling is often seen. The skin often looks somewhat bloated. Depending on the cause, eczema may have small, bulging blisters.

These contain clear liquid, for example. This is rather untypical for skin fungus between the toes and is more likely to be visible in case of an additional infection with bacteria. Eczema in the context of allergies or neurodermatitis also often affects other areas (e.g. the flexion sides of the arms and legs).

This is usually not the case with athlete’s foot; here, apart from the spaces between the toes, only other parts of the foot are usually affected. Frequently here are white, scaly tears on the cornea of the heels. The upper side of the foot is usually recessed.However, to clearly distinguish between athlete’s foot or eczema, you should consult your family doctor or dermatologist. With his experience he can better assess this and at the same time prescribe the necessary therapy!
