There are three typical variants of cutaneous mastocytosis: 1) urticaria pigmentosa (UP)/maculopapular cutaneous mastocytosis (MPCM), 2) diffuse CM, and 3) mastocytoma of skin.  UP/MPCM is the most common type and presents as brown or red macule or macule and papules with melanin pigmentation. Diffuse CM is almost exclusively in childhood and presents as diffusely thickened skin, pachydermia. Familial cases and germline mutations can be associated diffuse CM. Cutaneous mastocytoma is also known as solitary mastocytoma of skin, which is single or less than 3 lesions without predilection for presenting site. In addition, CM cannot be diagnosed if the features or criteria of systemic mastocytosis are met.
