What is Mastocytosis and Mast Cell Activation Disorders ?

Mastocytosis is a rare disorder characterized by abnormal accumulations of mast cells in skin, bone marrow, and internal organs such as the liver, spleen and lymph nodes. In the disorders of mast cell activation, mast cells are easily triggered to release their mediators, resulting in many of the same symptoms as systemic mastocytosis.
