小児の耳下腺腺房細胞腫の1例

Acinic Cell Carcinoma in a Child:Report of a Case

　はじめに

　腺房細胞腫は，臨床上再発および転移を認めることより悪性腫瘍に属する。好発部位は耳下腺で，その発生頻度は，全耳下腺腫瘍の2〜5％といわれている。この中で，小児の発生率は非常に低く，本邦の報告では3症例にすぎない^1）。今回われわれは小児に発生した耳下腺の腺房細胞腫を経験したので，文献的考察とともに報告する。

Acinic cell carcinoma is a low-grade malignant neoplasm in the salivary gland. A 9-year-old female patient complained of a swelling of her right parotid area for about a year. Acinic cell carcinoma was located in the superficial parotid gland and was excised with the surrounding normal tissue. She was not irradiated after surgery because the surgical margin was free of tumor. We have followed her for more than 3 years and there was no recurrence or metastasis.
