When actinic granuloma-like lesions appear in non-exposed areas, the rash is known as annular elastolytic giant cell granuloma. Though these can be easily distinguished based on histopathologic features and laboratory findings, the differential diagnosis includes tinea corporis , sarcoidosis , subacute lupus erythematosus , granuloma annulare ...
Histopathologically, an annular elastolytic giant-cell granuloma exhibits a granulomatous reaction accompanied by phagocytosis of the elastic fibers, elastolysis, and multinucleate giant cells devoid of or reduced in elastin fibers. Other hallmarks of the histopathology include the lack of mucin deposition and collagen necrobiosis. [7]
