METASTATIC LESIONS of the esophagus with symptoms of dysphagia are infrequently seen,1 and it is rare to find a case with x-ray findings simulating primary carcinoma. Gross and Freedman2 reported the first case of obstructing secondary tumor of the esophagus in 1942, and surveyed the literature, finding only 42 recorded cases of secondary tumors of the esophagus. In 1944 Toreson3 reported 7 cases he collected and found 19 others in the literature; of these 26 cases, less than half had evidence of partial or complete esophageal obstruction. There was little or no mention of x-ray findings in these cases.

The following case is one in which the clinical findings and x-ray appearance were those of a primary carcinoma of the esophagus; but postmortem examination proved the lesion to be an obstructing secondary tumor of the esophagus which metastasized from a hypernephroma of the left kidney.
