title: Hypercalcitoninaemia in a patient with urticaria pigmentosa. A possible cause of diarrhoea.
abstract: Mastocytosis gives rise to clinical symptoms such as flushing, itching and diarrhoea. We report a patient with urticaria pigmentosa without evidence of systemic involvement but with recurrent episodes of diarrhoea. The patient had elevated circulating levels of calcitonin, which might have been a mediator of her diarrhoea. We suggest that serum calcitonin level should be checked in patients with mast cell disease and diarrhoea.
