Annular lichenoid dermatitis of youth (ALDY), first described in 2003, represents an uncommon entity whose etiopathogenesis is still debated. Futhermore, the optimal treatment for ALDY is yet to be established. We report a 9‐year‐old girl who presented with annular and oval erythematous lesions mostly on her trunk, with several lesions on the neck, groin, flanks, and upper extremities. The lesions had histological and immunohistochemical features characteristic for ALDY. Treatment with H1‐antihistamines, topical corticosteroid, and UVB therapy was unsuccessful, while systemic treatment with cyclosporine induced complete remission.
