Skin rash on the inside of the forearm

The inner sides of the forearms are a typical localization for various rashes. A classic example of such a rash is neurodermatitis, also known as atopic dermatitis. In adolescents and adults, dry, scaly eczema appears on the flexion sides of the arms and legs as well as on other skin areas.

Itching is typical of eczema. In contrast, neurodermatitis in small children tends to affect the extensor sides. It is different with psoriasis.

This leads to eczema on the flexor sides of the arms, especially in small children, whereas adults typically develop rashes on the extensor sides. Psoriasis is also characterized by dry and scaly eczema, which itches in 2/3 of those affected. The two diseases are often confused.

Another disease affecting the inner side of the lower arms is scabies. The skin rash caused by scabies mites is characterized by very severe itching. In most cases, other parts of the body such as the spaces between the fingers and toes and the genital area are also affected.

Skin rash on the child’s forearm

Skin rashes in childhood are very common. Many viral diseases, including the classic childhood diseases, lead to skin rashes. However, the forearm is only one of many body regions affected by these diseases.

Rubella, measles, rubella and chickenpox are examples of such childhood diseases. Another common infection is scarlet fever, which apart from a spotty rash leads to tonsillitis with sore throat. A specific infestation of the forearms in children can be due to scabies.

It is caused by scabies mites and leads to itchy, red skin rashes on the flexion sides of the forearms. The spaces between the fingers and toes are also often affected. Finally, neurodermatitis must also be mentioned as the cause.

About 10 to 15 % of all children suffer from neurodermatitis. Thus it is a very common skin disease of childhood. Typical are itchy and dry skin areas on the flexion sides of the forearms. Neurodermatitis is often associated with allergies or asthma. In fact, food allergies can be found in 50% of cases in the affected children.
