Anyone here have treated mastocytosis?

Many doctors do: Mastocytosis of the skin is relatively common (esp. In childhood), and most dermatologists will be familiar with it. More extensive/complex skin disease, mast cell activation disoreders, or systemic mastocytosis (throughout the body, not just skin) should be seen by an expert. The mastocytosis society maintains a list of experts by region on their website (www.Tmsforacure.Org).
