Introduction We present the case of a 60-year-old patient with a tumorous change of the accessory salivary gland, which clinically showed as irritationless swelling of the right cheek.

Material and methods Clinical investigation, ultrasound of facial soft tissue, MRI of the skull. Operation and histological work-up. Clinical follow-up.

Results The 60-year-old patient reported a swelling on her right cheek for five weeks. In the bi-manual palpation of the right cheek a prallelastic, round, well-slidably mass could be felt anterior to the parotid gland. Sonography showed a buccal hypoechoic, sharply delimited, non-perfused mass with dorsal sound enhancement. MRI revealed a roundish, well defined mass which was hypointense in the native T1 images and moderately hyperintense in the native T2 images with clear enhancement. Intraoperatively, the mass was found within the accessory gland in the area of the Stensen duct. The excision was in toto. Histological processing showed an encapsulated tumor, which corresponds in character to a pleomorphic adenoma most closely. Further additional examinations are currently pending. The previous clinical follow-up examinations were regular.

Conclusion Tumors of the accessory salivary gland at the Stensen duct are very rare and account for about two percent of all neoplasms of the salivary glands. Of these, lymph node swelling, lipomas or vascular tumors of the cheek are to be distinguished. In addition to patient history and palpation, sonography is the imaging tool of choice. The treatment of choice is complete surgical excision.
