Granuloma annulare is a benign skin rash that appears as small circles of reddish bumps, often on the hands or feet. Its cause is unknown, but it has been linked to thyroid disorders and diabetes. Treatment is usually not necessary, but prescription topical creams can reduce the size and discoloration of bumps. It typically disappears on its own within one to two years.
Granuloma annulare is a type of benign skin rash that consists of small circles of reddish bumps. It usually appears on the backs of the hands or tops of the feet, although the rash can emerge elsewhere on the body. Doctors don’t have a clear understanding of why granuloma annulare develops, but it has been associated with thyroid disorders and diabetes. Rashes do not normally cause adverse physical symptoms, although a person may choose to have treatment for cosmetic purposes. Prescription topical creams are effective at reducing the size and discoloration of bumps.
The condition is most common in young children, although a person can potentially develop granuloma annulare at any age. It is usually isolated to a hand, forearm, or foot. The raised bumps are typically less than half an inch in diameter (about 1.25 cm) and emerge in ring-shaped groups. They are typically redder than the person’s normal skin tone. The condition can cause a slight itch, but the pain and other symptoms associated with the rashes are usually absent.
Most children and adults who get granuloma annulare are otherwise healthy, which makes the condition confusing for doctors. Some studies have found an increased risk of the condition in patients suffering from hormonal imbalances, thyroid disease, or childhood diabetes. Additionally, stress may play a role in the development and persistence of the rash. In most cases, granuloma annulare disappears on its own between one and two years after its onset.
A person who notices an unusual rash should visit their primary care physician to receive a proper diagnosis. A doctor can carefully examine the bumps and rule out other possible skin conditions. The shape of the rash sometimes resembles a ringworm infection, so a skin biopsy may be needed to check for the condition. After making a diagnosis, the doctor can explain the ins and outs of granuloma annulare and discuss possible treatment options with the patient.
Because granuloma annulare is not harmful, doctors usually discourage extensive treatment. Some people decide to seek out medical remedies to improve the appearance of their hands or feet. Prescription topical corticosteroids can help reduce inflammation, reducing bumps and promoting faster recovery time. Very large injuries can be cut or frozen from the body. Patients who have underlying health problems, such as thyroid disorders, may need to take specialized medications to manage their condition.
