Atypical Case of Granuloma Annulare / 대한피부과학회지

ABSTRACT

Granuloma annulare is a benign, usually self-limited chronic dermatasia of unknown cause, charaeterized by akin colored papules that may be arranaged in an annular configuraticn. Histopathologically, it is charicterized by camplete or incomplete foeal degeneration of collagen of chronic infliammatory cells. The authors obaerved an atypical case of granuloma annulare in a 4-year-old girl. She showed multiple papules and nodule on hands and feet. On inital examination, her skin lesions suggested histiacytosis, xanthanulama, rheumatoid nodule, or benign skin tumor. But the skin biopey revealed typica1 findings of granuloma awulare. Focal degeneration of colagen was confirmed by toluictine blue stain. Her skin lesions were almoatly cleared by skin biopsy and intralesional injectian of corticosteroid.
