An IgG4-Related Salivary Gland Disorder : A Case Series Presenting with a Different Clinical Setting

الملخص EN

Küttner tumor is a chronic inflammatory disease that presents with a firm swelling of the submandibular gland and often mimics a neoplasm.

Recently evidence suggests that Küttner tumor may be a type of disorder characterized by IgG4-related inflammations.

Herein, we report 3 cases of submandibular gland swellings with severe fibrosis, inflammation with marked lymphoplasmacytic infiltration; this pathology mimics clinical manifestation of a malignant tumor in 18-fluorodeoxyglucose positron emission tomography (FDG-PET) findings.
