A case of a male with sigmoid adenocarcinoma which accompanied with an isolated unilateral adrenal metastasis

Although the liver and the lung are the main metastatic sites, the incidence of adrenal metastasis from colorectal cancer in autopsy ranges from 1.9% to 17.4% according to different reports. The most common primary tumors that metastasize to the adrenal glands are the lung, kidney, breast, and rarely colorectal cancer. The alone adrenal metastasis due to colorectal carcinoma is very rare. Due to their rarity, on the basis of international literature and our experience of adrenalectomy could represent the current “gold-standard” therapeutic approach. In this report, we explain the case of a patient who presented with sigmoid cancer and one side adrenal metastasis without any other different distant metastases.
