What Is Granuloma Annulare?
1. Granuloma Annulare Causes
The specific causes of GA are unknown. Some research indicates that there may be a connection with the immune system. In addition, there is a potential hereditary component, as it sometimes runs in families. However, the means of inheritance has not thus far been discovered.
There are apparent triggers that are connected with the disorder’s onset. Exposure to sunlight for a lengthy period of time, insect or animal bites and minor skin injuries bring about the condition in some people. In others, the trigger may be an infection, vaccinations or tuberculin skin tests. Allopurinol and other drugs have also been associated with GA.
