Primary cervical ganglioneuroblastoma.
OBJECTIVE
Ganglioneuroblastomas represent a histological subgroup of the rare neuroblastic tumours with intermediate malignant potential arising from neural crest progenitor cells of sympathetic nerves. Diagnosis can often be difficult based on imaging alone. We describe 4 cases of children presenting with a solitary neck mass with histology ultimately revealing ganglioneuroblastoma.


METHODS
A retrospective case note review was carried out of all patients with cervical ganglioneuroblastoma seen at Great Ormond Street Hospital, UK.


RESULTS
Mean age at presentation was 5 years. Based on imaging, the initial diagnoses for three of the cases were: lymphatic malformation, carotid body tumour, paraganglioma, respectively, whilst the remaining case had an immediate incisional biopsy revealing the correct diagnosis. All cases were managed by surgical excision with no evidence of recurrence after a median follow up of 6 years.


CONCLUSIONS
Otolaryngologists should be aware of ganglioneuroblastoma when establishing the differential diagnosis of a child presenting with a neck mass. Biopsy is recommended as the gold standard investigation to avoid an incorrect diagnosis.
