title: Langerhans cell histiocytosis and hypercalcemia: clinical response to indomethacin.
abstract: OBJECTIVE
  Hypercalcemia is a known complication of childhood malignancies but has never been reported to be associated with Langerhans cell histiocytosis (LCH) in a pediatric patient.
  
  
  METHODS
  We describe an infant with multisystem LCH who developed hypercalcemia on two occasions. After being placed on indomethacin, the hypercalcemia did not recur despite disease progression.
  
  
  CONCLUSIONS
  Hypercalcemia may complicate LCH. If it is demonstrated, indomethacin should be considered as a treatment.
