Cystadenoma of the pancreas with cytomegalovirus infection in a female infant.

Cystadenoma of the pancreas, principally a disease of adult women, was found in a female infant. This benign, nonfunctional tumor is usually amenable to surgery and a cure is to be expected after extirpation. The pathogenesis of this mass is unknown, but the finding of a cytomegalovirus infection in an excretory duct at the tumor base in this case leads us to speculate that obstruction of the excretory duct is a possible cause.
