Rare secondary carcinoma from colon to testis. Review of literature and report of a new case.

A 65 year old man who underwent a right hemicolectomy for mucus secreting adenocarcinoma of the caecum in 1986 developed a secondary localisation in the right testis one year later. A review of the international literature shows only 14 previously described cases of spread of a colonic tumour into the testis. The Authors discuss the possible mechanisms of this form of dissemination.
