We report a case of chronic diarrhea due to hypergastrinemia with achlorhydria but without gastritis in a five-year-old boy. Symptoms responded promptly to oral administration of hydrochloric acid and resolved completely after one year of treatment. The pathophysiologic situation in this patient
The watery diarrhea-hypokalemia-achlorhydria syndrome associated with ectopic secretion of vasoactive intestinal peptide has only been conclusively documented with tumors originating in the pancreas or sympathetic chain. We report here the case of a 50-yr-old woman who developed this syndrome 3 wk
OBJECTIVE
To describe the rare occurrence of histologic transformation of a pheochromocytoma to a composite type of tumor during a long-term follow-up, which was complicated by watery diarrhea, hypokalemia, and achlorhydria syndrome.
METHODS
We report the case of a 12-year-old girl who presented
A 35-year-old man presenting with severe watery diarrhea was diagnosed as having the watery diarrhea, hypokalemia and achlorhydria (WDHA) syndrome with the elevation of plasma vasoactive intestinal peptide (VIP) level. Imaging diagnostic techniques revealed a hypervascular tumor at the tail of the
A 23-month-old girl with intractable diarrhea that had persisted for the past 6 months showed typical evidence of water-diarrhea-hypokalemia-achlorhydria (WDHA) syndrome. Serum vasoactive intestinal peptide (VIP)-like immunoactivity was very high, and urine homovanillic acid and noradrenaline were
A case of malignant pheochromocytoma, with a recurrence 15 years after adrenalectomy and with an associated watery diarrhea, hypokalemia, achlorhydria syndrome, is reported. Histological evaluation of the tumors revealed composite malignant pheochromocytoma-ganglioneuroblastoma (well differentiated
WDHA (watery diarrhea, hypokalemia, and achlorhydria) syndrome is an unusual paraneoplastic condition caused by excess vasoactive intestinal polypeptide (VIP) secreted by certain tumors. The onset of the syndrome is insidious, and diagnosis is usually delayed by months to years. Morbidity and
Mild hypokalemia is common and encountered in a multitude of diseases, but severe hypokalemia leading to rhabdomyolysis is relatively rare. The watery diarrhea, hypokalemia, achlorhydria (WDHA) syndrome caused by vasoactive intestinal polypeptide (VIP)-producing tumors, is an extremely rare cause of
A 45-year-old woman visited a local clinic with left-flank abdominal pain. Abdominal computed tomography (CT) revealed a tumor 20 cm in diameter in the left adrenal gland. She was referred to our hospital for further treatment. No endocrinological abnormality was detected on either serum or urine
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
BACKGROUND
A rare syndrome of watery diarrhea, hypokalemia and achlorhydria (WDHA) is usually caused by pancreatic endocrine tumors that secrete excessive vasoactive intestinal polypeptide (VIP). Here we report a rare case of WDHA caused by a pheochromocytoma.
METHODS
A 45-year old male presented
Three patients with the watery diarrhea-hypokalemia-achlorhydria (WDHA) syndrome were studied. All had watery diarrhea, hypokalemia and hypercalcemia. Plasma vasoactive intestinal polypeptide (VIP) levels determined by radioimmunoassay were markedly elevated in these patients, indicating that they
A case of WDHA syndrome accompanied by a pancreatic tumor in a 44-year-old Japanese male is presented, the 6th case in Japan. Clinically, the patient suffered from unremitting watery diarrhea, hypokalemia and achlorhydria with marked anemia and jaundice. The patient died of emaciation, dehydration
BACKGROUND
It has been reported that vasoactive intestinal peptide (VIP)-producing tumors accompanied by watery diarrhea, hypokalemia, and achlorhydria (WDHA) syndrome often produce multiple hormones biochemically and immunohistochemically.
METHODS
The authors examined the distribution of several
A patient is reported who had undergone right adrenalectomy for pheochromocytoma and 15 yr later developed a recurrence in the same site complicated by the watery diarrhea, hypokalemia, achlorhydria syndrome. This tumor was histologically defined as a composite malignant
