A toddler presents with patchy hair loss
What’s the management plan?
The diagnosis of AA is usually a clinical one, though assessment of alternative diagnoses is appropriate dependent on signs and symptoms. Workup of AA can include thyroid studies because of the association with autoimmune thyroid disease, though studies suggest limited screening benefits in children.11 Given its variable and unpredictable course, management can include “watchful waiting” because of its potential for spontaneous remission.6 For limited patchy loss, active treatment with mid to superpotent topical steroids or intralesional triamcinolone acetonide in older children and adolescents is reasonable.12 Other treatment options include topical or low-dose oral minoxidil and immunotherapy with diphenylcyclopropenone or squaric acid (inducing an allergic contact dermatitis).12 Management of therapies for more extensive AA is evolving, with ongoing studies of oral JAK-inhibitors and biologic agents.12,13
Our patient was started on topical fluocinonide 0.05% solution and achieved good disease control and hair regrowth over the course of 3 months.
