From 1973 to 1988, 1,104 patients with head and neck carcinomas (excluding thyroid carcinoma) were admitted to the Yokohama City University Hospital, and among them, 48 (4.3%) were under the age of 40 years.
We made a retrospective survey of these young patients.
There were 36 males and 12 females.
An increasing ratio of male to female was seen with increasing age.
The primary site was most frequently the nasopharynx (29 cases), followed by the maxillary sinus (9 cases), and the tongue (4 cases).
Squamous cell carcinoma in these young patients characteristically showed a low grade of differentiation.
