Abstract
AbstractA 70-year-old woman was admitted to our hospital for evaluation of melena and anemia. Three months previously, esophagogastroduodenoscopy was performed for suspected anemia, and a small gastric polyp was removed. During the patient's hospital stay several investigations were performed. Abdominal ultrasonography and abdominal computed tomography revealed a large mass on the superior pole of right kidney compatible with renal cell carcinoma. A further upper gastrointestinal endoscopy revealed the presence of several small gastric polyps and pearly duodenal mucosa. Colonoscopy revealed non-specific sigmoiditis. Biopsy of the gastric mucosa and of the abdominal mass showed the presence of clear cells, as a manifestation of renal cell carcinoma. We discuss the rarity of gastric metastases from renal cell carcinoma and its clinical presentation with digestive bleeding.
