[Whipple's disease with gastric and duodenal involvement. A new case]

Whipple's disease (WD) is a chronic multisistemic process in which the gastrointestinal tract is almost invariably affected. It is believed to be bacterial in origin, although a causative agent has not yet been isolated. Antibiotic treatment is usually quickly effective. We report a case of Whipple's disease in a 69-year-old man with typical clinical history and laboratory data. However, an associated allergic vasculitis not yet described in WD, the characteristical endoscopic appearance, and a partial response to treatment with persistence of histological lesions, made us consider of interest the report of the case.
