Sammanfattning
Whipple's disease is a chronic infectious disease that primarily affects the small intestine, but several organs can be involved simultaneously. The disease is caused by a gram-positive bacterium called Tropheryma whipplei. The disease is difficult to suspect because it is rare, and produces unspecific and long-term symptoms. Whipple's disease can lead to death if not treated. We here present a case of a man who presented with gastrointestinal symptoms in the form of diarrhea with blood, weight loss, fever, and lymphadenopathy and who was finally diagnosed with Whipple's disease 4 years after the occurrence of manifestations from the joints. The diagnosis was made both with 16S rRNA against Tropheryma whipplei and histopathologically from biopsy taken from the duodenum and distal ileum. The purpose of this case report is to raise awareness of a very rare disease that presented with a combination of symptoms similar to other and significantly more common diseases.
