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).
Therapies: Investigational
