Transitional cell carcinoma in a pelvic kidney associated with recurrent lung cancer

We report a case of transitional cell carcinoma of the renal pelvis arising in a pelvic kidney two years after resection of bronchogenic carcinoma. Primary cancer in a pelvic kidney has been rarely described and this is the second reported case of transitional cell carcinoma originating in a pelvic kidney and the first associated with recurrent lung cancer.
