Watery diarrhea, hypokalemia and achlorhydria (WDHA) syndrome caused by vasoactive intestinal polypeptide (VIP) -producing tumor only rarely occurs in patients with nonpancreatic disease. A 49-year-old woman was referred for evaluation of a right adrenal tumor incidentally diagnosed by abdominal ultrasound during the investigation of chronic watery diarrhea. Laboratory findings showed hypokalemia and excessive production of VIP and catecholamines. After surgical resection of the tumor, diarrhea subsided and both electrolytes and affected hormone levels normalized. Immunohistochemical examination confirmed a diagnosis of pheochromocytoma, which contained VIP-positive ganglion-like cells. We herein present the clinical and histogenetic implications of this rare clinical entity, with literature review.

Watery diarrhoea, hypokalaemia and achlorhydria (WDHA) syndrome was caused by vasoactive intestinal polypeptide (VIP)-producing tumour. A 3-year-old Chinese girl with watery diarrhoea, abdominal distension and hypokalaemia due to a thoracic paraspinal VIP-secreting ganglioneuroma is reported. The girl coughed, fevering up to 39 degrees C after a flu-like episode. She had eight to ten abundant stools daily which is not improved by dietary treatment, resulting in an important weight loss. She weighed 6.8 kg (nl P50 at 6 months of age) and is 76 cm (nl P50 at 9 months of age) in height. Blood electrolytes showed 129 mmol/L sodium, 2.42 mmol/L potassium, 94 mmol/L chloride and 18.6 mmol/L bicarbonate; urinary catecholamines were normal. Computed tomography scan evidenced a left side paravertebral mass of 4 x 6 cm in the lower thoracic region leading to the blood determination of vasoactive intestinal polypeptide which amounted 830 pmol/L(normal < 25 pmol/L). Surgical removal showed a ganglioneuroma of 160 g and was associated with disappearance of the diarrhoea and normalization of VIP level below 20 pmol/L. Review of the 63 reported cases in children with WDHA showed that many of the cases presented with non-treatable watery diarrhoea, hypokalaemia. Achlorhydria is not necessarily part of the WDHA syndrome. The male to female ratio is 1:1.5. Ganglioneuroblastoma and ganglioneuroma are the commonest tumours. Location of the tumour is variable: abdomen, chest or neck. Abdominal distension, flushing, episodic hypertension and colonic dilatation, constipation and ataxia were the other associated features. Surgical resection is the treatment of choice of VIP-producing tumours.
