Mastocytosis

In the early 20th century, all forms of Mast Cell Disease were undifferentiated and were grouped under the name "Mastocytosis." It means "an abnormal increase in the number of mast cells," but we now know that definition, taken from the root words, relates to some very specific mast cell disorders. Over the last 30 years, there has been an explosion of interest in, and research into. So, here are following general subcategories: Systemic Mastocytosis (Aggressive Mastocytosis , Indolent Mastocytosis, Mastocytosis with associated Hematologic Disorder, Mast Cell Leukemia); Cutaneous Mastocytosis ( Urticaria Pigmentosa, Telengiecstasia Macularis Eruptive Perstans); Mast Cell Activation Syndrome; common Pediatric Mast Cell Disorders (Solitary Mastocytoma, Urticaria Pigmentosa, Diffuse Cutaneous Mastocytosis).
