Solitary metastasis of colorectal cancer in the left adrenal gland 4 years after surgery on the primary tumor. Case report

Colorectal cancer (CRC) is one of the most common oncological diseases. On average, in 20–25% of cases after radical surgical treatment of CRC, the progression of the disease in the form of metachronous metastases in the liver and lungs, as the most common localization of CRC metastases, is noted in patients. With the advent of new drug treatment strategies for CRC, there is an increase in overall survival, as a result of which CRC metastases in the adrenal glands have become more common than previously thought, and the number of published reports of cases of CRC metastasis in the adrenal glands has increased. In this article, we report a rare clinical observation of metachronous solitary metastasis of CRC to the left adrenal gland 4 years after radical surgical treatment of the primary tumor: the patient underwent radical left-sided adrenalectomy. The period of observation of the patient without signs of progression and relapse of the disease is 6 months (at the time of publication).
