We present two cases of salivary duct carcinoma in this paper. Both cases were middle-aged men. They were treated with total parotidectomy and postoperative radiotherapy. Both cases have been followed up for 18 and 15 months respectively with no evidence of local recurrence or distant metastasis.
Sixty-six cases of salivary duct carcinoma, including ours, have been reported in the Japanese literature. We reviewed the clinical characteristics of this unusual tumor. Most cases were male (90％) and occured in the parotid gland (84％). The average age was 61 years, ranging from 36 to 91. In 44％ of patients, parotid tumors are accompanied by facial nerve paralysis. Total parotidectomy or extended parotidectomy followed by radiotherapy was the most common treatment for patients with salivary duct carcinoma in the parotid gland. The prognosis was poor and the 5-year survival rate was 28％.
Key words : salivary duct carcinoma, postoperative radiotherapy, parotid gland
