Answer

Types of cutaneous mastocytosis include solitary mastocytoma, diffuse erythrodermic mastocytosis, paucicellular mastocytosis (also termed telangiectasia macularis eruptiva perstans [TMEP]), and urticaria pigmentosa (UP). Urticaria pigmentosa is the most common form and is characterized by oval or round red-brown macules, papules, or plaques ranging in number from a few to thousands (see images below).
