Dermatographia

Dermatographia


Dermatographia is a condition also known as skin writing. When people who have dermatographia lightly scratch their skin, the scratches redden into a raised wheal similar to hives.

Dermatographia, which is sometimes called “skin writing,” refers to a condition in which seemingly minor scratches turn into temporary but significant reactions.

This condition is also called dermographism or dermatographic urticaria. Approximately 5 percent of people have this condition, and it’s most common in older children and younger adults.

Scratches can irritate your skin, but they tend to heal quickly. Some scratches are white against the skin, while others redden slightly. With dermatographia though, the scratches worsen, causing deep wounds or even allergy-like reactions.

Dermatographia is most often treated with antihistamines to reduce itchiness and overall discomfort. There’s no cure for this condition, although the symptoms don’t last long. Rare cases require more in-depth medical treatment from a dermatologist.
