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.
1973年至1988年期间，1104例头颈部癌（不包括甲状腺癌）患者入住横滨市立大学医院，其中48例（4.3%）年龄在40岁以下。我们对这些年轻患者进行了回顾性调查。其中男性36例，女性12例。随着年龄的增长，男女比例呈上升趋势。原发部位最常见于鼻咽部（29例），其次是上颌窦（9例）和舌部（4例）。这些年轻患者的鳞状细胞癌特征性地表现为低分化程度。
