For cutaneous mastocytosis four dermoscopic patterns have been defined: light-brown blot, pigment network, reticular vascular pattern, and yellow-orange blot.  Dermoscopic pattern varies depending on the subtype : In maculopapular mastocytosis, light-brown blot and pigment network predominate. In solitary mastocytoma, a yellow orange blot is typical. In all cases of telangiectasia macularis eruptiva perstans, a reticular vascular pattern is present. The reticular pattern of the vessels is even proved associated with an increased risk of need for daily use of anti-mediator medication. Therefore, dermoscopy in combination with other variables could provide additional help in the identification of patients at risk for more severe symptoms.
