ICD-11 definition : Dermographism is characterized by the development of short-lived itchy weals in response
to stroking of the skin. The weals are typically linear. Symptomatic dermographism
is triggered by light skin stroking or friction and is pruritic, whereas simple dermographism
is a common physiological response to firm skin stroking and is not pruritic.;
