Abstract:
Infiltration of sarcoid granuloma in old cutaneous scars is one of the uncommon cutaneous manifestations of sarcoidosis. Here, we report the case of a 47-year-old female who presented with swelling and irritation in 5 old scars. She had acquired these scars 9 years ago in a traffic accident. An incisional scar biopsy revealed noncaseating granulomas consistent with sarcoidosis. High-resolution CT (HRCT) revealed right paratracheal, both hilar, paraaortic, and subcarinal lymphadenopathy without any nodular densities in both lung fields. Successful regression of cutaneous inflammation was achieved using a short course of oral steroids.
