Abstract
A case of squamous cell carcinoma originating in Stensens’duct is presented. A 62-year-old man visited our hospital because of a swelling in his right cheek. At presentation, palpation of the lesion revealed a hard, elastic spherical mass 30 mm in diameter in the right cheek. Adhesion to the skin was found. However, the mobility of the surrounding tissue was poor. The buccal mucosa showed no abnormalities macroscopically. However, salivary flow was slightly poor. An aspiration biopsy revealed atypical keratinocytes, leading to the diagnosis of Class V,and squamous cell carcinoma was suspected. MRI revealed a 15-mm mass located mainly on Stensen’s duct. Neck dissection and resection of the parotid gland lamina superficialis resulted in complications which required further resection of the superficial layer of the masseter muscle and part of the skin of the cheek region. A platysma cervical flap was used to repair the defect. Histopathological examination of the resected tissue revealed a welldifferentiated squamous cell carcinoma. The patient received adjuvant postoperative radiotherapy at a total dose of 40 Gy. As of 14 months after operation, there has been no recurrence or sequelae.
