7 likes1,892 views
This document discusses several types of palisaded granulomatous dermatoses including granuloma annulare (GA), annular elastolytic giant cell granuloma, and actinic granuloma. It provides information on the presentation, associations, and treatments for localized and generalized GA. It also includes photographs and descriptions of GA lesions on the hands. Treatment options discussed include topical steroids for localized GA and tetracycline combined with nicotinamide or PUVA for generalized GA.
