A 75-year-old man underwent a right hemicolectomy for ascending colon cancer at age 72. Adjuvant chemotherapy was performed due to postoperative diagnosis of a high-risk stage IIb tumor. During the follow-up period, a bulge in the left inguinal region was observed and CT revealed a left spermatic cord tumor. Left orchiectomy was performed three years after the primary operation. Histological examination of the resected specimen revealed tubular adenocarcinoma, which was probably a metastasis from the ascending colon cancer. Based on the intraoperative findings of a high risk of recurrence, local radiation therapy and chemotherapy were performed. Spermatic cord metastasis from colon cancer is extremely rare and is associated with a poor prognosis. Metachronous metastasis can occur after a relatively long time and may be asymptomatic, often leading to delayed diagnosis. Spermatic cord metastasis should be considered in a patient with a malignant tumor who presents with an inguinal bulge.
