악하선에 발생한 Küttner 종양 1예

A Rare Case of Küttner Tumor Originating from Submandibular Gland

Küttner tumor is a benign inflammatory disease of the salivary gland that clinically mimics a malignant tumor because of its presentation as a unilateral painless hard mass. However the precise cause of this disease is still unknown. Pathologically, it is characterized by infiltration of IgG4-positive plasma cells. Also, it is accompanied with an elevated level of plasma IgG4. We report one case of Küttner tumor of the right submandibular gland in a 37 year old woman.
