Unclassified Mucinous Renal Cell Carcinoma: A Rare Histopathological Entity

Renal cell carcinoma (RCC) with mucin production is extremely rare. We present the case of a previously healthy 76-year-old woman who underwent a robotic-assisted laparoscopic right nephrectomy for a 5-cm heterogeneously enhancing right renal mass. Pathology revealed mucin-producing epithelial RCC. We discuss the presentation and pathological features of this case and comment on its definitive treatment.
