Mastocytosis is a disorder that occurs when there are too many mast cells in the body. Mast cells can be found in the skin, lymph nodes, internal organs (such as the liver and spleen) and the linings of the lung, stomach, and intestine. A mastocytoma or urticarial pigmentosa occur when these mast cells are in the skin. These usually are present soon after birth much like a freckle. When some patients have numerous lesions, they may have symptoms such as diarrhea, fainting or nausea.
