A Case of Scar Sarcoidosis Treated with Doxycyline / 대한피부과학회지

ABSTRACT

Scar sarcoidosis is a rarely encountering variant of cutaneous sarcoidosis and its pathogenesis is still unknown. When inactive scars that have been quiescent for years develop a red or purple hue with induration, we should doubt whether they become infiltrated with sarcoid granuloma or not. We report herein a 45-year-old patient with recurrent scar sarcoid, who shows indurated plaques on the right chin and raised serum level of angiotensin converting enzyme, although there was no evidence of systemic involvement. She was treated with oral doxycycline of moderate doses and skin lesions were cleared after 9 months of treatment.
