Abstract. – The coexistence of both kidney and colon primary malignancies is a rare condition. We report the case of a 75-year-old woman who presented with bilateral pulmonary nodules at chest X-ray and stratigraphy. Total-body CT scan showed multiple, apparently metastatic, bilateral pulmonary lesions, a diffusely dysomogeneous neoformation in the lower pole of the right kidney and a gross neoformation in the ascending colon. A right nephrectomy and a right hemicolectomy were performed and histology showed two primary neoplasms: clear cell renal carcinoma and undifferentiated adenocarcinoma of the colon.
