抄録

The authors reported a 31-year-old male suffering from a painless mass in the left submandibular region with eight months' duration. Examination revealed an elastic, hard mass which was movable and well-defined. The tumor and left submandibular gland were removed surgically. The tumor was encapsulated and measured 3.5-2. 5-2. 7 cm in size. Microscopically, it was a typical pleomorphic adenoma and consisted of adenomatous, myxomatous, and chondromatous elements.
Eighty-three cases of pleomorpic adenoma of the submandibular gland appearing in the Japanese literature were reviewed over a 70-year period.
The nomenclature, incidence, diagnosis and treatment of this tumor were discussed.
