The signs and symptoms of granuloma annulare skin diseases depend of the type of granuloma annulare, according to Mayo Clinic. Localized granuloma annulare, the most common variety, causes patients to have circular or semicircular reddish lesions on hands, feet, wrists and ankles, and tends to affect young women.
Generalized granuloma annulare, which makes up 15 percent of the cases, causes lesions over a large part of the body, including the trunk, arms and legs, Mayo Clinic reports. This type primarily affects adults and is sometimes itchy.
Subcutaneous granuloma annulare usually affects children, Mayo Clinic explains. Instead of producing a rash, this variety creates a hard lump under the skin that is usually less than 1.5 inches in diameter.
Patients with granuloma annulare should visit a doctor if their symptoms do not go away after two weeks, Mayo Clinic advises. Treatment also should be sought if the lesions form in ring patterns. Most of the time no treatment is necessary for granuloma annulare. The rash usually disappears after a couple of months but can last as long as two years.
Treatment options include using prescription corticosteroid creams or ointments to improve the appearance of the condition and speed up healing, Mayo Clinic states. Corticosteroid injections, light therapy and freezing the lesions can also speed up healing.
