Atopy
Atopy
Atopy (/ˈætəpi/; from the Greek atopos, meaning "out of place") is a predisposition toward developing certain allergic hypersensitivity reactions. Atopy may include allergies to inhaled substances such as dust mites (atopic asthma) and pollen (hay fever), as well as food allergies and eczema.
Etymology
The term "atopy" was coined in 1923 by Coca and Cooke, from the Greek atopos meaning "out of place". This was in reference to the unusual reactions of the immune system in people with atopy, which seemed to be "out of place" or abnormal.
Pronunciation
Atopy is pronounced as /ˈætəpi/.
