Duodenal Bleeding from Metastatic Renal Cell Carcinoma

Abstract: Massive upper gastrointestinal bleeding due to malignancy is relatively uncommon and the duodenum is the least frequently involved site. Duodenal metastasis is rare in renal cell carcinoma (RCC) and early detection, especially in case of a solitary mass, helps in planning further therapy. We report a case of intractable upper gastrointestinal bleeding from metastatic RCC to the duodenum. The patient presented with melena and anemia, 13 years after nephrectomy for RCC. On esophagogastroduodenoscopy, a submucosa… Show more

“…RCC metastases represent 7.1% of these lesions and are most frequently located in the periampullary region or the duodenal bulb (3, 4, 10). Metastatic lesions to the pancreas are uncommon, accounting for only 5% of all pancreatic malignancies (7).…”

“…Sixty-nine percent of patients with solitary GI metastasis from RCC present with GIB, but massive GIB is a rare occurrence (Ohmura et al, 2000). An ulcerative metastatic mass in the duodenum is the main cause of GIB (Rustagi et al, 2011;Chang et al, 2004;Cherian et al, 2011). Duodenal involvement with pseudoaneurysm formation as the cause of GI bleeding has also been reported in patients with clinical history of RCC in the literature (Blake et al, 1995).…”

“…Generally, an immune cell-inhibiting mechanism is present in the microcirculatory environment of tumors (20). A trace number of cancer cells of RCC were latently present under the control of the immunological surveillance mechanism, but it may have manifested because the DLBCL tumor volume rapidly increased and inhibited immunity, and the subsequent growth of metastatic cancer cells from RCC may have been slightly rapid, unlike the slow growth previously reported (1,6,17).…”

“…According to the review of Rustagi et al (17), the mean duration post nephrectomy to diagnosis of solitary duodenal metastases was 7.9±4.7 years (median 8 years). RCC can metastasize for a long period of disease latency after nephrectomy, via the lymphatic or hematogenous route, as well as by peritoneal dissemination or direct invasion into adjacent anatomic structures (18).…”
