Histopathologic Features of Giant Cell Arteritis in an Actinic Granuloma Lesion

Abstract

The association between actinic granuloma and giant cell arteritis (temporal arteritis) has been claimed by some authors. There is a hypothesis that actinic radiation has the principal role in the etiology of both diseases in a similar way. Here, we report a case of actinic granuloma that had characteristic pathologic features of giant cell arteritis in histopathologic examination without clinical evidence of giant cell arteritis.
