Alopecia Areata

A. Alopecia areata is characterized by asymptomatic, noninflammatory, non-scarring areas of complete hair loss, most commonly involving the scalp, but the disorder may involve any area of hair-bearing skin.

B. Auto-antibodies to hair follicles is the most likely cause. Emotional stress is sometimes a precipitating factor. The younger the patient and the more widespread the disease, and the poorer the prognosis.

C. Regrowth of hair after the first attack takes place in 6 months in 30% of cases, with 50% regrowing within 1 year, and 80% regrowing within 5 years. Ten to 30% of patients will not regrow hair; 5% progress to total hair loss.

D. Lesions are well defined, single or multiple, round or oval areas of total hair loss. Typical "exclamation point" hairs (hairs 3-10 mm in size with a tapered, less pigmented proximal shaft) are seen at the margins.

E. Differential diagnosis: Tinea capitis, trichotillomania, secondary syphilis, and lupus erythematosus.

F. A VDRL or RPR test for syphilis should be obtained. A CBC, SMAC, sedimentary rate, thyroid function tests, antinuclear antibody should be done to screen for pernicious anemia, chronic active hepatitis, thyroid disease, lupus erythematosus, and Addison's disease.

G. Therapy. Topical steroids, intralesional steroids, and topical minoxidil may be somewhat effective.
