Juvenile polyposis of the stomach causing recurrent upper gastrointestinal bleeding.
We present the case of a 42-year-old man who suffered from recurrent severe upper gastrointestinal bleeding starting from February 2003. Endoscopy showed multiple glassy polyps in the stomach, which corresponded to a diffuse mucosal thickening detected by endosonography. The duodenum was normal. In February 2006, life-threatening acute gastrointestinal bleeding prompted total gastrectomy. The resection specimen showed the gastric mucosa carpeted by numerous glassy pedunculated polyps, measuring 2 cm in largest diameter. Histologically, the polyps were characterized by an abundant loose stroma and by elongated, twisting foveolae, covered by hyperplastic epithelium. Colonoscopy including the terminal ileum revealed a single tubulovillous adenoma, but no hamartomatous polyps, rendering a final diagnosis of juvenile polyposis of the stomach. This case represents the first description of juvenile polyposis causing life-threatening gastric haemorrhage. Thus, although rare, the disease has to be considered in the differential diagnosis of patients with acute upper gastrointestinal tract bleeding.
