Water Clear Cell Parathyroid Adenoma: Case Report and Literature Review

Water clear cell parathyroid adenoma is a rare cause of primary hyperparathyroidism. In this rare disease entity, normal parathyroid tissue is replaced with growth of water-clear cells, instead of the chief cell hyperplasia associated with the majority of parathyroid adenomas. We present the case of a water clear cell parathyroid adenoma in a 54 year old woman with symptomatic hypercalcemia, as well as a review of the literature on this rare disease. This constitutes the 17th reported case of water clear cell parathyroid adenoma.
