Granuloma annulare is a harmless skin condition that is commonly seen in women, children and young adults.
Understanding Granuloma Annulare
Granuloma annulare is characterized by red or skin colored raised bumps that occur in a circular or annular pattern. The lesions can be mistaken for pimples or fungal infections such as ringworm.
Although harmless, granuloma annulare lesions can become large and widespread. They commonly develop on the hands and feet but can also be found on other body parts.
Symptoms of Granuloma Annulare
Granuloma annulare may present as a single lesion or multiple lesions. Lesions present as bumps in an annular to semi-annular configuration . The small, firm bumps are usually not accompanied by other symptoms, although some individuals do experience mild itching.
Rarely, granuloma annulare appears as a single small, hard nodule or a widespread rash covering large portions of the body.
Diagnosing Granuloma Annulare
A dermatologist is often able to diagnose granuloma annulare on visual exam. Atypical cases may require a skin biopsy to confirm diagnosis.
Treatment of Granuloma Annulare
Most cases of granuloma annulare may resolve within a few months to two years without treatment. Corticosteroid creams or injections placed directly into the lesions may be used to speed the healing process.
Other treatment options includes freezing the lesions with liquid nitrogen, use of light or laser therapy and, and for widespread cases, immunosuppressive medications may be used.
