未成年に生じた唾液腺上皮性腫瘍の検討

Salivary gland epithelial tumors in children and adolescents

はじめに

　成人例における唾液腺腫瘍は稀ではなく，諸施設より多くの報告がなされているが，小児・若年者における発生頻度は低く，日常診療において遭遇する機会も少ない。成人同様，根治性と顔面神経の取り扱いが重要となるが，悪性例において低悪性度癌の占める割合が高いこと，良性腫瘍のほとんどが多型腺腫であることなどの特徴があり，これらを念頭に置いて診断治療にあたる必要がある。今回，当科で加療を行った未成年唾液腺上皮性腫瘍症例について検討したので報告する。

　Epithelial tumors of salivary glands in children and adolescents are rare. We reported on 20 children and adolescents with salivary gland epithelial tumors treated in our hospital from 1990 to 2015. There were 14 parotid gland tumors and 6 submandibular gland tumors. Histologically, 17 tumors were benign and three were malignant. All of the benign tumors were pleomorphic adenoma except for one case of Warthin tumor. Histologic types of malignant tumors were mucoepidermoid carcinoma in two cases and basal cell adenocarcinoma in one. In the group of malignant tumors, one patient died for local recurrence.
