Association of Distal Renal Tubular Acidosis with Hypercalcemia; Report on Three Cases

Background: hypercalcemia is an endocrine emergency that should be diagnosed as soon as possible and managed carefully. for better management multiple causes of hypercalcemia must be taken into consideration.case presentation: we observed three infants with hypercalcemia and distal renal tubular acidosis at the time of diagnosis during 5 years. the patients were referred with severe dehydration and failure to thrive.conclusion: there was no reason for hypercalcemia found in these patients except distal renal tubular acidosis. so we suggest distal renal tubular acidosis as a cause for hypercalcemia.
