Skin rash on forearm

Definition

In principle, skin rashes can appear on the most varied parts of the body. Sometimes they show symptoms such as itching, although rashes are often asymptomatic. The lower arm is relatively often affected by a rash.

Both the front and the extensor side of the forearm can be affected by a variety of rashes. Many rashes of the forearm show a localization typical of the disease, so that some are more restricted to the flexor or extensor side. A rash of the forearm is often not limited to the forearm, but can also affect other parts of the body, such as the upper arm, hand or even the trunk. In many diseases, the forearm is only one of many body parts affected by the rash.

Causes

The causes of a skin rash on the forearm are manifold. Some rashes only affect the forearm, while others are spread over other parts of the body. At this point, some causes that can cause a rash on the forearm are presented.

• Infections: A number of different infections can be the cause of a rash on the forearm. Within the framework of the classic childhood diseases measles, rubella, rubella ring, chickenpox and scarlet fever, the forearms are usually involved. However, other regions of the body, such as the face and trunk are also affected by the rash.

  General symptoms such as fever, a feeling of illness and aching limbs are also involved. Apart from the classic childhood diseases, other infectious diseases are also involved. These include syphilis.

  The patchy skin rash of syphilis is often restricted to the hands, feet and forearms and typically does not show any itching.

• Atopic Dermatitis: Atopic dermatitis, also known as neurodermatitis, is characterized by an itchy, dry and scaly skin rash, which is mainly found in the crook of the arm. It occurs mainly in childhood and adolescence.
• Psoriasis: Psoriasis, which is also called psoriasis, is often confused with neurodermatitis, but usually does not appear until an advanced age. Typical are itchy, red, scaly skin rashes on the extensor sides of the arms.

  Furthermore, yellow-brownish changes on the nails are almost always found.

• Allergy: An allergy can lead to itchy, reddish skin rashes on the forearms. Usually, however, the entire body or at least other parts of the body are affected. Typically, the skin symptoms are not sharply demarcated from the surrounding healthy skin.
• Contact dermatitis: Contact dermatitis is a rash caused by contact of the skin with allergenic or toxic substances.

  Common allergens include nickel or fragrances. Wearing latex gloves can also lead to a rash on the forearm. Toxic contact dermatitis, which is caused by contact with “toxic” substances, is always sharply limited to the contact area.

• Skabies: The scabies, colloquially known as scabies, causes severe itching and burning of the skin.

  It is caused by the so-called scabies mites and is highly contagious. The lower arms, especially the flexor sides, can be affected. The spaces between the fingers and toes and the genital region are also frequently affected.
