A 3 year old Chinese girl with watery diarrhoea, abdominal distension and hypokalaemia due to a thoracic paraspinal vasoactive intestinal peptide (VIP) secreting ganglioneuroma is reported. The pre-operative serum VIP was 314 pmol/l (normal less than 30). Her diarrhoea stopped after the removal of the tumour. The VIP was 14 pmol/l 6 months post-operatively. Review of the 19 reported cases in children with documented elevated serum VIP showed that many of the cases presented with watery diarrhoea for prolonged duration before the diagnosis was made. Earliest age of onset was 2 weeks of age. The male to female ratio was 9:10. Ganglioneuroma and ganglioneuroblastoma were the commonest tumours. Pancreatic non-beta cell hyperplasia and neurofibroma were also reported. Location of the tumour was variable: neck, chest or abdomen. Increased urinary catecholamine excretion was reported in 50% of the cases. Abdominal distension, flushing, episodic hypertension and failure to thrive were the other associated features.

An 8-month-old boy with persistent watery diarrhoea and failure to thrive developed abdominal distension, hypokalaemia, and flushing of the face and trunk. A high concentration of vasoactive intestinal peptide-like immunoreactivity was found in the serum. Soon after resection of a suprarenal mass, the serum level of vasoactive intestinal peptide became normal and the diarrhoea stopped. Histologically the tumour was a ganglioneuroblastoma: the cells showed fluorescence by the indirect immunofluorescence technique with anti-vasoactive intestinal peptide serum. Electron microscopical examination showed abundant secretory granules in the tumour cells. Reports of chronic watery diarrhoea in children due to neural crest tumours are reviewed, with particular respect to the clinical features of the syndrome.
