Abstract
Although spontaneous regression of metastatic renal cell carcinoma occurs, it is so uncommon that it should not be considered the primary basis for recommending removal of the asymptomatic primary lesion. Such a recommendation should be made when other treatment modalities are available to augment the factors influencing the patient-tumor inter-face. Spontaneous regression of a documented solitary liver metastatic lesion is reported. Removal of the residual hepatic lesion failed to prolong the patient''s life.
