Sumario:Adenomyomatous hyperplasia is an extremely rare lesion encountered in the ampulla of Vater. Less than 50 cases have been described, most of them with clinical consequences of biliary obstruction, misdiagnosing it as a malignancy. The authors present a concomitant case with a renal tumor, its diagnosis, management, and clinical relevance, as well as a brief revision of the literature. Ampullar and renal tumors were found in a 74-year-old female, in the imagiologic study of a low back pain, in the emergency department. Both were considered malign after further study, and pancreatoduodenectomy with partial nephrectomy was proposed. There is no accurate diagnostic tool to differentiate the benign nature of adenomyomatous hyperplasia and extensive operations are often performed. As an incidental finding in the study of another tumor, this case raises the concern about which and how to treat both tumors, taking into account the morbidity of the respective interventions.
