Abstract
Sarcoidosis is a granulomatous disorder that mostly involves the lungs. Bilateral hilar lymphadenopathy (LAP) and lung infiltration are commonly observed in these patients. However, other organs such as the skin, liver, and eyes may also be involved. The exact cause of sarcoidosis is still unknown. Sarcoidosis is diagnosed with non-caseating, non-necrotic epithelioid granulomas on histology and its typical clinical and radiological presentations. However, other differential diagnoses of sarcoidosis such as lymphoproliferative disorders and infectious diseases should be excluded. We herein report a case of a 47-year-old male who was initially diagnosed with lymphoma but upon further diagnostic workup, sarcoidosis was established as the definite diagnosis.
