Whipple's disease: a case study with unexpected prognosis.

Due to the systemic nature of Whipple's disease, its clinical presentation may be highly variable. The diagnosis may, therefore, be unduly delayed. Untreated, Whipple's disease is still potentially lethal. Although it traditionally presents with signs and symptoms of small intestine involvement, such as diarrhea and malabsorption, Whipple's disease can involve many other organs. Typically, the diagnosis is established by biopsy of the small intestine. The authors describe a case of Whipple's disease in order to stress the importance of bearing this polymorphic disease in mind, with special emphasis on its possible lethal outcome in spite of therapy.
