A patient comes with 6months history of painless bilateral swelling of the face which has been progressively increasing in size. On routine CXR, he is found to have perihilar lymphadenopathy. What is the most probable diagnosis?

The key is E. Mikulicz’s disease. [Mikulicz’s disease (MD) is a well-known disorder characterized by enlarged lacrimal and parotid glands caused by infiltration with lymphocytes. When no specific cause is found it is called Mikulicz’s disease; and if secondary to disease like sarcoidosis it is termed as Mikulicz’s syndrome].
