There was a significant correlation between the result of TUNEL and clinical course in patients with sarcoidosis. Apoptosis in epithelioid histiocytes and inflammatory cells seems to participate in the course of granulomatous inflammation. Further studies are needed to determine the role of Fas, FasL and other regulatory factors in apoptosis in the granulomatous inflammation in pulmonary sarcoidosis. ER -
