Epidermoid cysts of the liver.

To the four recorded cases of epidermoid cysts of the liver are added two cases recently seen in children. One was in a 4-yr-old girl and associated with biliary cirrhosis. The other was in a 5-mo-old boy. The former was treated by roux-en-y cystjejunostomy, the latter by enucleation. The origin of these cysts is unknown. One theory suggests derivation from accessory foregut buds. Because of their malignant potential, treatment should be by excision. Where this is impossible, roux-en-y cystjejunostomy offers satisfactory palliation.
