HISTORY
The original description of mastocytosis was by Nettleship and Tay, who told of a 2-year-old girl with hyperpigmented papules that spontaneously urticated. Eight years later, in 1877, Paul Ehrlich formally discovered the mast cell. The next year, Sangster suggested the name โurticaria pigmentosaโ. Unna was the first to demonstrate that mast cells were responsible for the cutaneous findings in mastocytosis patients.
