Granuloma annulare is a benign granulomatous disease which has an unknown etiology and it is represented by typical annular lesions. Recently various therapeutic modalities have been suggested such as intralesional injections of steroid, chloroquine, dapsone, surgical excision and so on. But any satisfactory result has not been reported yet. In the first case, a 65 year-old-man, Polycyclic, erythematous patches with raised edges were noted on the upper arm spreading to the trunk and both lower extremities for the past 3 years. In the second case, a 63-year-old man, numerous match-head sized skin-colored papules were detected on the sun exposed area such as both shoulders, upper extremities and hands dorsum for the past 3 months. On the histological examination of back, hands dorsum respectively, incomplete degeneration of collagen bundles surrounded by lymphocytes, histiocytes in a palisade pattern and a few giant cells were found in the dermis. Two patients were treated with systemic PUVA, one for 2months and the other, 4months. (Korean J Dermatol 2001; 39(4): 454~458)
