Bowel metastasis from lung cancer has rarely been described. In this study, we report on a 72-year-old man with squamous cell carcinoma of the lung and his status post-operation. He was noted to have tarry stool and decreased levels of hemoglobin. A colonoscopy was performed and a biopsy of a descending colon lesion showed metastatic squamous cell carcinoma. On F-18 fluoro-2-deoxy-D-glucose positron emission tomography/ computed tomography (F-18 FDG PET/CT) images, an intensely FDG-avid colon lesion was compatible with a metastatic lesion. In addition, several focally intense FDG-avid lesions were found in the small bowel with corresponding mass-like lesions on CT images. Metastasis to the small bowel was highly suspected.

肺癌遠處轉移至小腸的案例報告很少。本文報告一位72歲男性患有鱗狀上皮肺癌，發現黑便跟持續血紅素降低。大腸鏡檢查發現降結腸病灶，經病理切片診斷為轉移性鱗狀上皮癌症。正子斷層造影顯示除了降結腸葡萄糖強烈攝取病灶外，小腸也有多處局部葡萄糖強烈攝取病灶，並伴隨電腦斷層影像上呈現腫塊狀病灶，因此高度懷疑癌症也同時轉移至小腸。
