Sarcoidosis in the elderly

Sarcoidosis is a granulomatous disease with unknown causes, activated T lymphocytes and monocyte macrophages at the affected site, and involving multiple systems. Clinically, bilateral hilar lymphadenopathy and lung involvement are the most common, followed by eye and skin involvement. Lesions can also affect lymph nodes, liver, spleen, heart, parotid gland, bones and other organs in other parts. The diagnosis of this disease depends on histopathological confirmation, and excludes tuberculosis, fungal infection and other granulomatous lesions. Glucocorticoids are the main therapeutic drugs that can inhibit the formation of inflammation and granulomas, relieve clinical symptoms, and control the progression of the disease.
