title: Solitary adrenal metastasis in a patient with sigmoid colon cancer; report of a case.
abstract: A 73-year-old man had sigmoidectomy for sigmoid colon cancer in December 2001. Although he was followed regularly with chemotherapy, his serum carcinoembryonic antigen (CEA) increased on August 2002. Abdominal computed tomography and magnetic resonance imaging showed a right adrenal mass and no other abnormality. The preoperative diagnosis was a solitary adrenal metastasis from sigmoid colon cancer; the lesion was removed in September 2002. On pathology, adrenal metastasis was confirmed. Although the patient's serum CEA normalized soon thereafter, 12 months after adrenalectomy, the CEA again increased; the patient had local recurrence of the resected adrenal lesion and liver metastasis. Therefore, the patient was given systemic chemotherapy, but his condition deteriorated, and he died 38 months after adrenalectomy. Adrenal metastasis from colorectal cancer is not unusual; however, a solitary metastasis is rarely found and resected surgically. As surgical treatment of the metastatic lesion could improve patients' prognosis to some extent if it is detected early, the possibility of adrenal metastasis should be kept in mind when colorectal cancer patients are followed.
