We report the rare case of a patient with solitary metastasis to the spermatic cord from colon cancer. The patient was in his seventies who had undergone right hemicolectomy (RHC) for transverse colon cancer (T4a, N2, M0 Stage IIIb) and received adjuvant chemotherapy. Two years after the RHC, he presented to us with a mass in the left groin ; CT revealed a solitary enhancing lesion measuring 2 cm in diameter. He was administered neoadjuvant chemotherapy, followed by laparoscopic resection of the left spermatic cord. Histopathological examination showed moderately differentiated tubular adenocarcinoma of the spermatic cord, the histology of the lesion being identical to that of the previously diagnosed transverse colon cancer. Therefore, a diagnosis of left spermatic cord metastasis from colon cancer was made. Although adjuvant chemotherapy was also administered, the patient returned one and a half years later with recurrence of the lesion in the left inguinal region and metastasis to a left external iliac node. Laparoscopic resection of the left external iliac lymph node and resection of the left inguinal mass through an incision in the groin were performed. Currently, he is undergoing chemotherapy because of a recurrence in the para-aortic lymph nodes without any symptoms. Key words:colorectal cancer,spermatic cord metastasis,laparoscopic excision
