Sarcoidosis is a systemic inflammatory disorder of unknown etiology characterized by the presence of noncaseating granulomas. Scar sarcoidosis refers to the infiltration of old scars with noncaseating epithelioid cell granulomas. This reactivation of old scars, manifesting as cutaneous sarcoidosis, is highly specific for sarcoidosis and very unusual. This report describes an old scar with an unusually long history of quiescence and its reactivation after 35 years along with manifestations of pulmonary sarcoidosis.
