Renal cell carcinoma presenting as an upper gastrointestinal bleeding.

An 80-year-old man presented with melaena and anaemia of 1 week duration. This was associated with shortness of breath and an indigestion-type pain for the preceding 8 weeks. General physical examination revealed epigastric tenderness, but an otherwise soft abdomen with no organomegaly. The patient had a gastroscopy, showing a polypoidal lesion in the second part of duodenum (D2) as the bleeding point, which was managed with epinephrine injection and endoclips. This was followed by CT of the abdomen, revealing a lobulated 8 cm mass arising from the lower pole of the right kidney and invading the duodenum. The case report aims to acknowledge the possibility of direct duodenal involvement in renal cell carcinoma, which is a rare occurrence.
