Answer

Arcuate dermal erythema is an uncommon form of granuloma annulare that manifests as infiltrated erythematous patches that may form large, hyperpigmented rings with central clearing. Papules are a less prominent feature in this variant. Patches typically appear on the trunk and may spread centrifugally over weeks to months.
