| Abstract: | A 56-year-old Japanese man in whom a descending colon carcinomahad been resected underwent a high orchitectomy for metastaticepididymis from the colon. Metastatic carcinoma from the digestiveorgans to the spermatic cord (SC) and/or the intrascrotal contents(ISC) is rare. Fifty-four Japanese patients with metastasisfrom the digestive organs to the SC and/or the ISC were analyzed.The most frequent primary site was the stomach and the mostfrequent metastatic site was the spermatic cord. Our patientwas the first to exhibit metastasis from the colon to the epididymis.A primary site was identified in 24 patients subsequent to themetastatic tumor. Twenty patients had other organ metastatis.The prognosis for SC and/or ISC metastasis patients is poor.Our patients has survived for 18 months following his orchitectomywith no other organ metastasis (31 months after the primaryoperation). In our patient, monoclonal estrogen receptor stainingwas negative; however, further study must be undertaken. |
