Growing occult synchronous adrenal metastasis from rectal cancer after surgery and during adjuvant chemotherapy: A Case Report
ABSTRACT We report a case of an occult synchronous adrenal metastasis of rectal cancer. A left adrenal mass was found by computed tomography
(CT) 6 months after low anterior resection for rectal cancer. This lesion was growing during adjuvant systemic chemotherapy.
The level of serum carcinoembryonic antigen and that of adrenal hormones were within the normal range. Radical left adrenalectomy
was performed, and histopathological examination revealed metastatic adenocarcinoma compatible with rectal cancer. Adrenal
metastasis is not rare in autopsy series. The possibility of adrenal metastasis should be considered in the follow-up of rectal
cancer patients. Surgery may be the treatment of choice in occult synchronous metastasis of adrenal gland in rectal cancer.
