Renal papillary necrosis in thyroid carcinoma.
A thirty-four-year-old man with progressive visual impairment was found to have thyromegaly and renal insufficiency at the time of admission. Subsequent evaluation demonstrated bilateral optic neuritis and a thyroid nodule which proved to be a follicular carcinoma. Nephrologic studies revealed bilateral papillary necrosis and chronic interstitial nephritis on biopsy. The patient's renal function stabilized and twenty-four-hour protein excretion diminished after hemithyroidectomy. Carcinoma-related protein production may have played a role in the development of the observed renal lesions. Carcinoma should be a consideration in patients with unexplained papillary necrosis.
