title: Photosensitive annular elastolytic giant cell granuloma with cutaneous amyloidosis.
abstract: Annular erythematous indurated plaques with central clearing developed on sun-exposed areas of a diabetic patient. The lesions were aggravated by sun exposure. Histological examination revealed features as described in annular elastolytic giant cell granuloma. In addition, subepidermal amyloid deposits were identified. Though a coincidental occurrence cannot be excluded, a possible pathogenetic relationship between the two conditions is postulated. It is believed that they are caused by actinic damage to skin altered by diabetes.
