There are three main forms of the condition: maculopapular cutaneous mastocytosis (also called urticaria pigmentosa), solitary cutaneous mastocytoma, and diffuse cutaneous mastocytosis. There is also an exteremely rare form called telangiectasia macularis eruptiva perstans. The signs, symptoms and severity of the condition vary by subtype.|

For cutaneous mastocytosis four dermoscopic patterns have been defined: light-brown blot, pigment networkGrid-like pattern consisting of interconnecting pigmented lines surrounding hypopigmented holes., reticular vascular pattern, and yellow-orange blot.  Dermoscopic pattern varies depending on the subtype : In maculopapular mastocytosisThis glossary term has not yet been described., 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 patternA lesion with a reticular pattern has typical pigment network throughout the entire lesion. of the vesselsThis glossary term has not yet been described. 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.
