[Stenon's or Stensen's duct carcinoma].

Carcinomas arising from the Stensen's duct are extremely rare, and only 28 cases have been reported since 1927. Only two cases of the whole were adenoid cystic carcinoma like our case. A 83-year-old man with painless tumour of the left cheek is reported. The tumour was removed without facial nerve injury via extended parotidectomy incision and after superficial lobectomy.
