title: Castleman disease of the mesentery as the great mimic: Incidental finding of one case and the literature review.
abstract: Castleman disease is an uncommon benign lymphoproliferative disorder characterized by hyperplasia of lymphoid follicles. More commonly described in the mediastinum, its occurrence in the mesentery is exceedingly rare, which is easily to be ignored in differential diagnosis when an abdominal mass is found. We report the case of an asymptomatic 71-year-old woman with a homogenous and hypervascular mass at the inner side of duodenojejunal junction. Based on the clinical suspicion of a gastrointestinal stromal tumor, a surgical resection was performed. Final diagnosis of the mass was hyaline vascular variant of Castleman disease. Here, we summarize the clinicopathological and radiological features of this disease by literature review, which may be helpful to bring awareness of this entity and improve the clinical decision making when similar scenarios are encountered.
