Re-evaluation of histological findings of nonparasitic splenic cysts.

Objective: The pathogenesis of nonparasitic splenic cysts (NPSCs) has not been clarified completely. The aim of this multinational and multicentre retrospective study was to further elucidate the origin of NPSCs.

Methods: From 1980 to 2006, 50 children and adolescents were surgically treated for NPSC at six paediatric surgical centres in four European countries.
