Abstract

ABSTRACT: A previously healthy 37-year-old man had evaluation of abdominal pain, which had persisted after abrupt onset with fever and hematuria. Although the fever and hematuria had spontaneously resolved after 1 week, the abdominal pain had worsened over a 4-month period. Predicated upon computed tomography and with a presumed diagnosis of renal cell adenocarcinoma, left radical nephrectomy was done. Histopathologic analysis was negative for malignancy but compatible with inflammatory pseudotumor of the urogenital tract—a pathologic entity that is common in the urinary bladder and prostate gland but is rarely diagnosed in the kidney.
