[Gluten-sensitive enteropathy and intestinal non-Hodgkin lymphoma (author's transl)].

The case report is presented of a patient with gluten sensitive enteropathy who subsequently developed an intestinal non-Hodgkin lymphoma. When steatorrhoea or diarrhoea develops in a patient with abdominal lymphoma, these symptoms are often attributed to progression of the lymphoma or to chemotherapy of the lymphoma. Since there is an established relationship between gluten-sensitive enteropathy and intestinal lymphoma, the differential diagnosis of steatorrhoea or diarrhoea developing in the course of malignant intestinal lymphoma must include gluten-sensitive enteropathy as well. In the investigation for gluten-sensitive enteropathy HLA typing can be used as a screening test in addition to routine malabsorption tests and small bowel biopsy
