A Case of Generalized Granuloma Annulare with Perforating and Subcutaneous Granuloma Annulare / 대한피부과학회지

ABSTRACT

We present a case of generalized grannuloma annulare with perforating and subcutaneous forms which occurred in a 15-year-old girl. Two years ago, multiple umbilicated, match head to pea sized, erythematous papules were noted on the upper extremities. Then the patient also experienced crusted or ulcerated erythematous papular lesions on the lower legs. Recently, tender, subcutaneous nodules appeared on both soles. The biopsy specimens from the skin lesions of the hand and the sole showed typical findings of granuloma annulare in the dermis and the subcutis, respectively. On the histopathological examination of the calf lesion, palisading granuloma as well as transepidermally eliminating dermal collagenous and necrotic material were seen. The skin lesions were almost completely improved by treatment with dapsone, 100mg a day, for 8 weeks orally.
