Mastocytosis
Mastocytosis
For cutaneous mastocytosis four dermoscopic patterns have been defined: light-brown blot, pigment network, reticular vascular pattern, and yellow-orange blot. [1] [2]
Dermoscopic pattern varies depending on the subtype [2]:
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.
