title: Parathyroid cyst: case report of a rare surgical lesion of the neck.
abstract: A thirty-two year old female presented with a neck mass of probable thyroid origin. Repeated fine needle aspirations failed to provide diagnostic tissue or long-term resolution of the cystic mass. The clinical and pathologic findings in this case of a parathyroid cyst are presented. Parathyroid cyst is a rare cause of neck mass. Recurrence of a cyst is also unusual following aspiration. The aspiration of clear watery fluid from a neck mass offers presumptive evidence of a parathyroid cyst. The demonstration of parathyroid hormone in the cyst fluid is considered diagnostic.
