[Retroperitoneal ganglioneuroma in childhood].
OBJECTIVE
An incidentally discovered retroperitoneal ganglioneuroma in a 4-year-old child is presented.


METHODS
Ultrasonography and CT were performed. The surgical specimen was analyzed by macroscopic, histological and immunohistochemical techniques.


RESULTS
US and CT localized a retroperitoneal mass independent from the left kidney and adrenal gland. The histological study showed a fascicular proliferation with myxoid and fibrillar areas mixed with mature ganglion cells. These cells were positive for neurofilament and neuron specific enolase. The patient had a favorable outcome with no signs of tumor recurrence.


CONCLUSIONS
Ganglioneuroma is a rare, completely mature tumor that has to be differentiated from neuroblastoma.
