Eponym

Historically, bilateral parotid and lacrimal gland enlargement was characterized by the term Mikulicz's disease if the enlargement appeared apart from other diseases. If it was secondary to another disease, such as tuberculosis, sarcoidosis, lymphoma, and Sjögren's syndrome, the term used was Mikulicz's syndrome. Both names derive from Jan Mikulicz-Radecki, the Polish surgeon best known for describing these conditions. In more recent times, the terms "Mikulicz's disease" and "Mikulicz's syndrome" were viewed as ambiguous and outdated by some sources. Today Mikulicz's disease is considered to be a subtype of IgG4-related disease, usually accompanied by involvement of one or more other organs in the body.
