Idiopathic Anaphylaxis (IA) - Sufferers experience repeated Anaphylaxis but no underlying cause can be identified.

Urticaria Pigmentosa (UP) - In which Mast Cells accumulate in clusters in the skin giving rise to a rash which may or may not irritate.

Telangiectasia Macularis Eruptiva Perstans (TMEP) - A sub classification of UP and Cutaneous Mastocytosis in which the blood vessels in the skin are dilated and can appear as webs or spots.
