Abstract
- Granuloma annulare (GA) is a benign granulomatous disease. Although its etiology is not well understood, there are some reports about GA occurring after specific conditions such as sunburn, a tuberculin test, insect bites, viral diseases and trauma. Especially, in case of the auricular region which is vulnerable to trauma, it seems that GA has some relation with trauma. In 1992, Mills and Chetty proposed that repetitive minor trauma may be an important cause of auricular GA. Among the 5 cases of auricular GA that have been reported in the English literatures, 3 cases are assumed to be associated with repetitive minor trauma. Herein, we report on two cases of auricular GA that were thought to be associated with repetitive minor trauma.
