Renal cell carcinoma presenting with upper gastrointestinal bleeding: A case report

Area of Science:

• Oncology
• Gastroenterology
• Radiology

Background:

• Renal cell carcinoma (RCC) incidence is rising, often detected through cross-sectional imaging.
• Metastasis occurs in 20%-30% of diagnosed RCC cases.
• Small bowel metastasis from RCC is exceptionally rare.

Observation:

• This report details a rare case of metastatic RCC.
• The patient presented with upper gastrointestinal bleeding as the initial symptom.
• The metastasis was located in the small bowel.

Findings:

• Metastatic renal cell carcinoma can present atypically.
• Upper gastrointestinal bleeding can be an initial sign of small bowel RCC metastasis.
• This case underscores the importance of considering rare metastatic sites.

Implications:

• Highlights the diagnostic challenge of rare metastatic presentations of RCC.
• Emphasizes the need for comprehensive evaluation in patients with unexplained gastrointestinal bleeding.
• Contributes to the limited literature on small bowel metastatic RCC.
