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.
