“…29 White dermographism is commonly seen in patients with atopic dermatitis, characterized by white linear scratches on the local skin along the affected area, and it may be related to local vasoconstriction; 48,49 black dermographism is characterized by the appearance of black lines on the local skin after contact with certain metal products. [50][51][52] Moreover, dermographism may also occur in immune diseases, such as mast cell activation syndrome, adult-onset Still's disease, primary biliary cirrhosis, and antiphospholipid antibodies. We should consider whether the patient has extracutaneous symptoms such as abdominal pain, myalgia, arthralgia, fever, lymphadenopathy, thrombus, scleral icterus or others.…”

Dermographism is a common subtype of chronic urticaria. It generally manifests as a linear wheal after scratching or friction, with or without angioedema. The pathophysiology is not clear, but currently, we believe that the stimulation of the skin by mechanical stress leads to the activation of mast cells, which provoke the release of histamine and pro‐inflammatory mediators, ultimately forming wheal along the stressed area. The gold standard for diagnosis is a medical history and provocation test or dermatographic test. As one of the subtypes of chronic urticaria, the Urticaria Control Test (UCT), Chronic Urticaria Quality of Life questionnaire (CU‐Q2oL), and Dermatology Life Quality Index (DLQI) are also effective tools for evaluating disease control in dermographism patients. In addition to avoiding triggers, nonsedating H1 antihistamines are the first‐line medications recommended by EAACI and other guidelines; for those who do not respond to standard doses, the recommended dosage can be increased up to 4 times. When necessary, the off‐label use of omalizumab can be considered, and some drugs with potential therapeutic effects are still being explored. However, there is still a lack of biomarkers for predicting disease severity, efficacy, and prognosis. Here, we review what we know about dermographism and some points that need exploration in the future.

“…These very small metal particles absorb light and do not reflect it, hence appear as dark black. [ 5 ] We believe, in our case household detergents, environmental dust, or application of talcum powder after wet work may have played a role in the induction of BD. In general, it is difficult to produce BD on naturally oily skin than dry skin.…”
