title: [Whipple's disease with normal intestinal histology: rarity or reality?].
abstract: Whipple's disease has been diagnosed more frequently in recent years as a consequence of better awareness and of improved diagnostic tools. The number of case reports of Whipple's disease without gastrointestinal symptoms and without histological lesions of the intestinal mucosa is increasing. Therefore, the traditional perception of this disease as well as the methods for its diagnosis need to be revised. We report on 2 patients with Whipple's disease who had systemic inflammatory reactions but neither gastrointestinal symptoms nor an abnormal duodenal histology. Whipple's disease was diagnosed on the basis of extraintestinal tissue histology (lymph node, vertebral body) and by polymerase chain reaction, and was treated successfully with antibiotics. Recommendations for diagnostic procedure in Whipple's disease with both typical and atypical clinical presentation are discussed.
