Simultaneous occurrence of IgG4-related chronic sclerosing dacryoadenitis and chronic sclerosing sialadenitis associated with lymph node involvement and warthin's tumor

Chronic sclerosing dacryoadenitis and chronic sclerosing sialadenitis have been shown to belong to the group of diseases referred to as IgG4-related sclerosing disease. The authors report a case of the simultaneous occurrence of IgG4-related sclerosing disease in both lacrimal and submandibular glands, clinically simulating malignant lymphoma. A cervical lymph node and a Warthin's tumor were also involved. This unique case of multiple organ involvement in IgG4-related sclerosing disease is documented.
