Red marks on the back of a 61 year old Hispanic female patient in a case of dermographism, also known as dermatographic urticaria. This is an allergic reaction where the skin is hypersensitive to touch. Normally this sort of allergic response is only associated with some irritants but in dermatographism any object can evoke a response. | |
