Answer

Patients with actinic annulare present with 1-10 plaques, which tend to be annular or serpiginous areas with raised erythematous borders. Lesions may be hypopigmented centrally; the epidermis is otherwise spared. Plaques are typically distributed over sun-exposed areas, such as the arms, neck, face, and dorsa of the hands. Other than by their location on heat- or sun-damaged skin, actinic annulare lesions are difficult to distinguish clinically from eruptions of granuloma annulare.
