Unusual presentations of enlarged parathyroid cysts: two case reports.

INTRODUCTION

Parathyroid cysts are infrequently encountered and have a variable presentation pattern depending on their size, location and secreting character.

PATIENTS AND

METHODS

We report two cases of parathyroid cysts characterized by their uncommon clinical presentation.

RESULTS

In the first case the patient presented with a large cervical cystic mass without hypercalcemia, while in the second case, the patient experienced a hypercalcemic crisis associated with acute renal failure. The variable pattern of clinical manifestations is discussed.

CONCLUSION

Parathyroid cysts are a rare entity. Surgical resection is the key to therapy when hyperparathyroidism or local compression are identified.
