Clinical manifestations of ganglioneuroma

Ganglioneuroma may occur spontaneously or after therapy for neuroblastoma. This lesion may be metastatic or unresectable in the primary site. The rarity of this situation and lack of understanding of the biology of this benign condition may lead to extensive, potentially life-threatening attempts at surgical resection or the futile use of chemotherapy or radiotherapy to try to cause regression or control growth. The authors present here several cases which demonstrate the multiple presentations of ganglioneuroma and the potential problems which may arise in their management.
