[Whipple disease and non-Hodgkin lymphoma].

6 years ago a 60-year-old man had been suffering from chronic diarrhea, weight loss and epigastric pain. Some years before he had developed joint pain, symmetric at both hands and feet. Duodenal biopsy and PCR reaction revealed Whipple's disease. Treatment with Co-trimoxazole for more than 21 months achieved remission. 6 years after diagnosis of Whipple's disease the patient presented with multilocal lymphadenopathy. Malignant Non-Hodgkin-Lymphoma (Centrocytom) stage PS IV b was diagnosed. COP-chemotherapy (Vincristine, Cyclophosphamide, Prednisone) achieved partial remission up to now. Whether the appearance of the malignant lymphoma is a consequence of Whipple's disease or a second neoplastic disease remains to be answered by further epidemiological studies.
