A Rare Case of Spermatic Cord Metastasis Following Surgery for Transverse Colon Cancer

We report a rare case of spermatic cord (SC) metastasis in a 44-year-old man with a history of transverse colon cancer. He had undergone laparoscopic right hemicolectomy followed by adjuvant chemotherapy and remained under routine follow-ups with no signs of recurrence. He presented with painless right scrotal swelling, and imaging revealed an SC tumor (SCT). Serum tumor markers were within the normal ranges. Radical orchiectomy was performed, and histopathology confirmed metastatic adenocarcinoma from the transverse colon. Local recurrence was detected four months postoperatively, and the patient is currently receiving multidisciplinary treatment. Metastatic SCTs, although rare, need to be considered in patients with a history of gastrointestinal cancer, even without elevated tumor markers.
