Since cancer is considered by its very nature to be a progressive, relentless, irreversible disease, successful treatment is obviously dependent on complete obliteration or extirpation of all malignant cells, either at their primary site of origin or in metastatic sites accessible to various forms of therapy. The appearance of distant metastases after initial definitive treatment suggests disseminated malignancy, generally tantamount to a hopeless situation.

Such a case is herein reported.
