Dermatographism vs. Scabies. Scabies looks like lines of burrows on skin made with little mounds or blisters. They cause itching which is often worse at night. Although they can be anywhere on skin they like going into skin folds (waistline, axilla, breasts, between fingers, feet, wrists, knees, elbows, buttocks ; genitalia. Dermatographic urticaria (aka dermatographism, skin writing) is when scratching or rubbing.
