Abstract
A 77-year-old woman underwent a left hemicolectomy for transverse colon cancer. Histopathological examination revealed poorly differentiated adenocarcinoma (SS, N1, H0, P0, M0, Stage IIIa). The patient then received adjuvant chemotherapy for 6 months (capecitabine and oxaliplatin). Nine months after the hemicolectomy, computed tomography (CT) revealed a tumor in the left adrenal gland. Positron emission tomography-CT did not detect any other metastatic lesions. The patient was diagnosed as having solitary adrenal metastasis, and a left adrenalectomy was performed. Pathological findings of the resected specimen indicated metastatic adenocarcinoma from the colon cancer because of the similarities between the histological characteristics of the two lesions. The patient is still alive at 12 months after the adrenalectomy with no evidence of recurrence.
We report a rare case of solitary adrenal metastasis from colon cancer. Surgical resection might improve the prognosis of such lesions.
