| pubmed-article:8275801 | pubmed:abstractText | Eleven cases of salivary duct carcinoma were studied clinicopathologically. The clinical features are as follows: men outnumber women; arise most frequently within the parotid glands; rapidly enlarging mass; obvious symptoms of invading nerves; high rates of cervical lymph node and distant metastases; poor patient's prognosis. Its histologic features were shown by the various stages of development of duct carcinoma including dysplasia, carcinoma in situ, papillary, cribriorm, solid and commedo patterns. In addition to the intraductal carcinoma, there is the invasive carcinoma with obvious infiltration into the surrounding tissues. Its treatment requires the combination of radical surgery with postoperative radiotherapy. | lld:pubmed |
