|Description||This chapter describes dermoscopyThe examination of [skin lesions] with a 'dermatoscope'. This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. of cutaneous mastocytosisis a form of mastocytosis that primarily affects the skin. 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 patternsThis glossary term has not yet been described. 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 networkThis glossary term has not yet been described. predominate. In solitary mastocytoma, a yellow orange blot is typical. In all cases of telangiectasia macularis eruptiva perstans, a reticular vascular pattern is present.
