Rare Scar Sarcoidosis: A Dermatologic Masquerader
Keywords:
Sarcoidosis, Granuloma, Scar, Fine Needle Aspiration Cytology (FNACAbstract
Infiltration of sarcoid granuloma in old cutaneous scars is one of the uncommon cutaneous manifestations of sarcoidosis. Here, we report the case of a 32-year-old female who presented with pain and swelling in 9 month old appendicectomy scar. An incisional scar biopsy revealed granuloma. On query she had inflammatory polyarthritis and persistant dry cough for last 2 months. High-Resolution CT (HRCT) revealed right paratracheal, both hilar, paraaortic and subcarinal lymphadenopathy with pulmonary nodular densities in both lung fields. FNAC from mediastinal node revealed non caseating granuloma consistent with Sarcoidosis. Successful regression of cutaneous inflammation was achieved using a course of oral steroids, hydroxychloroquine and methotrxate. The onset of scar sarcoidosis is rare and, therefore, not well understood; however, inflammatory alterations inpreexisting scars may be important
indicators for disease onset
