title: [Papillary nephrocarcinoma: radiographic and echographic aspects].
abstract: Between 1976 and 1987, 395 patients with kidney tumors were studied with radiological techniques and sonography. In 37 cases (9.4%) histopathology diagnosed pure papillary renal cell carcinoma. Analyzing the radiographic patterns of these neoplasms, the authors observed constantly diminished vascularity (100%), frequent calcifications (35.1%) and necrotic areas (51.3%). Such X-ray features are not specific: nevertheless, their coexistence is strongly suggestive of papillary renal cell cancer. No consistent US pattern was found; however, necrotic areas were easily demonstrated in most cases. It must be stressed how patients with papillary carcinoma experienced a longer postoperative survival; it has not yet been established whether such favorable behavior is due to low biological aggressiveness or to earlier diagnosis.
