Castleman's disease of the duodenum
Castleman's disease is a rare lymphoproliferative disorder of uncertain origin. Just two cases of Castleman's disease of the gastrointestinal tract have been reported. These were found in the stomach. However, as far as we know, Castleman's disease of the duodenum has not been reported. This is the first report of hyaline vascular subtype of Castleman's disease at the duodenum.
