Abstract
A 74-year-old woman underwent a low anterior resection for rectal cancer with multiple lung metastases. After she had received chemotherapy with six courses of mFOLFOX6 regimen, multiple lung metastases disappeared and she was judged to have a complete response, and maintained as a complete response for 6 years after the surgery. In 6 years and 6 months, CEA marker was elevated and abdominal CT revealed solitary right adrenal metastasis. She underwent a resection of right adrenal gland. The adrenal tumor was confirmed a metastasis from the rectal cancer by pathological examination. Solitary adrenal metastasis of colorectal carcinoma is rare and has no characteristic clinical symptoms, and thus early diagnosis based on imaging findings is difficult. There is a high risk of recurrence in other organs in patients who have undergone for cases of adrenal gland metastasis from colorectal cancer. Thus, chemotherapy and radiotherapy should be considered as treatment options as well as surgery for cases of adrenal gland metastasis from colorectal cancer.
