Mediastinal lymph node metastasis of colon cancer: Report of a case

We herein describe a patient with mediastinal lymph node metastases which o ccurred after both a primary sigmoid colon cancer and metachronous ovarian metastasis had been resected. The most likely route of metastases to the me diastinum in this case is the paravertebral venous plexus probably connecte d to the ovarian metastasis, or so-called remetastasis. This case illustrat es that the mediastinum is thus a possible metastatic site in patients with colon cancer. Surgeons should therefore pay attention to the mediastinum a s well as the lung fields when checking chest X-ray films during a follow-u p of patients after a resection of colon cancer.
