Аннотация
This report describes a salivary duct carcinoma (SDC) arising from the extraglandular portion of the Stensen duct. The patient was a 56-year-old man who presented with a palpable, elastic, hard mass without tenderness in the right cheek. Computed tomography revealed a tumor of the extraglandular portion of the Stensen duct. Supraomohyoid right neck dissection and total right parotidectomy were performed, and the histologic diagnosis was SDC of the Stensen duct. Postoperatively, the patient received no additional treatment. Neither recurrence nor metastasis was observed during 4 years of follow-up examination. SDC of the Stensen duct is extremely rare. To our knowledge, there is no report that describes primary SDC arising from that location. We also believe this is the first report that describes the clinical course of primary SDC arising from a Stensen duct.
