口蓋扁桃に転移した大腸癌の1例

Metastatic Tonsillar Tumor due to Mucinous Carcinoma of the Transverse Colon

I．はじめに

　口蓋扁桃に発生する悪性腫瘍の多くは原発性であり，転移性腫瘍は稀である^1）。

　今回われわれは，左口蓋扁桃に転移をきたした大腸粘液癌の1例を経験したので，文献的考察を加えて報告する。

　A 69-year-old man complained of throat discomfort. On examination,a white coating mass was found in the left palatine tonsil. He had a surgery of transverse colon cancer two years ago and the histopathological diagnosis was mucinous carcinoma. The histopathological findings of the tonsillar mass was adenocarcinoma producing mucine. Thus the tonsillar mass was diagnosed as metastasis from mucinos carcinoma in the abdomen. The patient died of metastasis to the brain three months after tonsillar metastasis was found.
