Giant Abdominal Mass: Papillary Renal Cell Carcinoma with Metastases to the Bladder, Omentum and Perigastric Tissue

Abstract

Papillary renal cell carcinoma is an uncommon malignant tumor, which rarely metastases to the bladder and/or omentum. We report the case of a 71-year-old woman with macrohematuria for two years and a large mass on the right flank. Thus, we present a brief review of the literature regarding the classification, clinical manifestations, diagnosis, immunohistochemical profile, and treatment of this neoplasm. Special attention was given to the role of immunohistochemistry, which was decisive for the determination of multiple metastases, as well as the study by imaging exams, which defined the best surgical approach.
