title: [Parathyroid cysts: reprot of 2 cases and review of the literature].
abstract: Although parathyroid cysts are rarely described in the literature, they should be considered in the differential diagnosis of cysts occurring in the anterior compartment of the neck. We report two cases. The presence of elevated parahormone in the clear fluid aspirate is the diagnostic criterion. Parathyroid cysts may be functional, probably resulting from cystic formation of a parathyroid adenoma, or non function with their own epithelial lining, probably arising from remnants of the pharyngeal pouch or Kursteiner's canal. Search for both hypercalcemia and hypophosphoremia are needed. Fine needle aspiration provides the diagnosis and is also the treatment of choice for non-functional parathyroid cysts. Aspiration of functional cysts can reduce the hormone level to normal prior to surgical removal.
