[Diarrhea, protein-losing enteropathy and sarcoidosis].

A case of inactive sarcoidosis associated with protein-losing enteropathy, severe hypoalbuminemia and diarrhea is reported. 99mTc-labeled human serum albumin was performed to show protein loss. There was no abnormal upper gastrointestinal mucosa as shown by peroral duodenal and jejunal biopsies. However, a CT scan showed the presence of multiple calcified intra and retroperitoneal lymph nodes, which might explain the presence of lymphatic ectasia and protein-losing enteropathy in this case. A brief literature review of gastrointestinal sarcoidosis is included.
