Various Sonographic Findings of Kuttner Tumors of the Bilateral Submandibular Gland and Right Parotid Gland

ABSTRACT

Chronic sclerosing sialadenitis or a Kuttner tumor is a benign inflammatory condition characterized by firm swelling of the salivary gland. This disease may clinically mimic Sjogren's syndrome or a salivary gland origin neoplasm. Various sonographic findings in patients with a Kuttner tumor were described in previous studies. Here, we describe a rare case of a 60-year-old man presenting with a non-tender right-sided parotid mass and swelling of both submandibular glands. A pathologic examination of the lesions in the right parotid gland and both submandibular glands indicated the presence of Kuttner tumors of various sonographic appearances.
