A Case of Solitary Right Adrenal Metastasis from Rectal Cancer
2019
An 86-year-old woman underwent laparoscopic high anterior resection for RS rectal cancer. Histological examination showed tub2-por, pT3, pN2a, Stage B disease. Given the age of the patient, adjuvant chemotherapy was not administered. Five months after the surgery, her carcinoembryonic antigen(CEA)level was elevated and a 42x25mm mass was detected in the right adrenalby computed tomography(CT). Metastasis from rectalcancer was suspected but no other lesions were detected by positron-emission tomography(PET)-CT. Nine months after the surgery, laparoscopic right adrenalectomy was performed. Histological examination revealed that the right adrenal tumor had moderately-differentiated adenocarcinoma very similar to the primary rectalcancer; therefore, the right adrenall esion was diagnosed as metastasis from the previous rectalcancer. The tumor marker levelreturned to normall evelafter the second surgery. The patient was discharged on the 8th post-operative day but declined adjuvant chemotherapy due to her age. Six months later, liver, lung, and peritoneal metastasis were identified by CT. We report this case of solitary adrenalmetastasis from rectalcancer resected by laparoscopic right adrenalectomy.
