[Endoscopic and pathological aspect of small bowel and colonic involvement in Whipple's disease: a case report].

We describe a case of Whipple's disease confirmed by clinical, histological, bacteriological and molecular criteria. The duodenal involvement was associated with the presence of an endoscopic and histological enterocolitis. Final diagnosis of small bowel and colonic involvement by Whipple's disease was confirmed by histology and molecular biology. We review the literature on extra duodenal involvement. We underline the fact that enterocolitis in Whipple's disease is non-specific. We also discuss the other causes of intestinal mucosal infiltration by macrophages.
