Mesothelial Inclusion Cyst in an Infant with Beckwith-Weidemann Syndrome

Abstract

Mesothelial inclusion cysts are rare benign tumors not frequently reported in the literature. When reported, they are primarily found in adults. One report from 2006 reports an association with Beckwith-Weideman syndrome, but no other reported cases discuss this correlation. We describe a case of an infant with Beckwith-Weideman syndrome who, in the setting of omphalocele repair, was found to have hepatic cysts with pathology revealing mesothelial inclusion cysts.
