A Case of Granuloma Annulare Occurring on Herpes Zoster / 대한피부과학회지

Granuloma annulare is a benign, granulomatous disease that presents clinically as papules and plaques, often in an annular configuration. It has been reported following tuberculin skin tests, insect bites, sun exposure, trauma, and various viral diseases. Several types of cutaneous lesions have previously been described at the site of herpes zoster scars. These include granuloma annulare, lymphoma, pseudolymphoma, granulomatous diseases, and lichen planus. We report a case of granuloma annulare at a herpes zoster scar site.
