Background: Differential diagnosis of cystic mass in the neck include thyroid cyst, thymic cyst, thyroglossal duct cyst, branchial cleft cyst, bronchogenic cyst, lymphangioma and parathyroid cyst (PC). Parathyroid cysts are rare and account for only 0.5% of all parathyroid pathologies. Case Report: A 30-year-old female with insidious onset anterior neck cystic swelling was diagnosed as benign parathyroid mass. Conclusion: Parathyroid cysts should be taken into consideration while evaluating asymptomatic neck masses.
