Renal cell carcinoma presenting with Melena from direct invasion into the duodenum: a case report and a review of literature.

ABSTRACT

Today the classic triad of flank pain, hematuria and a palpable abdominal mass is rarely present at initial diagnosis of renal cell carcinoma due to the growing number of cases diagnosed incidentally on imaging studies. We report a case of a 58-year-old female who presented with melena where a subsequent esophagogastroduodenoscopy demonstrated a bleeding duodenal lesion. Pathologic study of a biopsy revealed Clear Cell RCC and an ensuing abdominal CT revealed the direct duodenal invasion of a primary renal mass. We also provide a brief review of nephrectomy in the face of metastatic renal cell carcinoma.
