GRANULOMA ANNULARE |
|
|
DESCRIPTIONGranuloma annulare is a chronic skin disorder characterized by lesions that appear in the shape of a ring. This is not malignant or contagious. The skin on the bottoms of feet and backs of fingers, and on the hands, arms, elbows, legs, and knees is involved. Granuloma annulare can affect all ages but is most common in children (4 to 12 years).
Appropriate health care includes:
Self-care after diagnosis.
Physician's monitoring of general condition and medications, which may include injections of steroid medications into lesions.
SIGNS & SYMPTOMS
Papules (small raised bumps on the child's skin) with the following characteristics:
Papules have a domed or slightly flat shape, 3mm to 6mm in diameter.
Papules are non-scaling.
Papules are pink or violet. Those on the lower extremities are darker than ones on other parts of the child's body.
Papules don't itch or hurt the child.
Multiple papules cluster in a ring. Ring diameters range from 1cm to 10cm. Papules around the ring border are close but don't grow completely together. This gives the border a beaded appearance. The ring's center is often darker than the edge. Ringed lesions change in size and shape over a period of several weeks to 6 months.
CAUSES
Unknown.
RISK FACTORS
Injury to the child's skin, including sunburn.
PREVENTING COMPLICATIONS OR RECURRENCEYour child should avoid injury to the skin. Protect the child's skin from sunburn with sunscreen or clothing.

MEDICATION

If your child's skin becomes dry and itchy, provide additional moisture by covering the affected area with a damp, clean cloth before applying the plastic wrap. You may also soak the affected area briefly in water after applying medicine to the child.
Ask your doctor how often to change the plastic dressing.
Reapply medicine every time you change the plastic dressing.
