Granuloma Annulare is a benign, chronic skin disorder characterized by elevated spots (papules) or nodules that form a ring with normal or slightly depressed skin in the center. Symptoms Granuloma annulare is characterized by small, firm, yellowish or skin-colored nodules arranged in a ring on the skin. They are most common on the back of the hands and feet, the ankles, knees, or elbows. The disorder can be chronic with possible remissions and/or recurrence of spots. Causes The exact cause of Granuloma Annulare (GA) is not known. The disseminated type of the disorder which affects large areas of the body may be associated with Diabetes Mellitus. Granuloma Annulare may also be a complication of pseudorheumatoid nodules or shingles (Herpes Zoster). Some forms of GA tend to run in families (familial), but the exact mode of inheritance has not yet been determined. (For more information on the above disorders, chooses "Diabetes Mellitus" and "Herpes Zoster" as your search terms in the Rare Disease Database. Affected Population Granuloma Annulare is more common in females than in males. The disorder may occur in children and adults. Related Disorders Symptoms of the following disorder can resemble those of Granuloma Annulare. They may be useful for a differential diagnosis: Eruptive Xanthoma is characterized by clusters of small yellow or yellowish-brown elevated spots over the entire body. The clusters may be encircled by a red ring. This disorder may be distinguished microscopically from Granuloma Annulare by the different coloring of its histiocyte cells. Therapies: Standard Usually the eruptions of Granuloma Annulare disappear without treatment (spontaneous remission). Treatment for chronic forms of the disorder include the antibacterial drug dapsone, and isotretinoin, which is the synthetic form of retinoic acid (related to vitamin A).
