Granuloma annulare is a benign, often persistent skin condition characterized by inflammation that results in elevated, discolored rashes or subcutaneous lumps. When it persists for an extended period, it can cause emotional distress.
Rashes typically appear on the hands, feet, forearms, and elbows, and the condition most commonly affects young adults. Some medications and minor skin injuries may trigger it. The condition is non-contagious and usually painless, but it can significantly affect an individual’s self-esteem.
Without intervention, granuloma annulare can last from a few weeks to several decades. Treatment can help improve the skin’s appearance, but the raised bumps often return. Common treatments include medications and procedures.

However, there is evidence to suggest that it may be related to an inappropriate immune system response following skin injury. Additionally, certain factors are believed to potentially trigger granuloma annulare, including:
