Surgical management of recurrent parathyroid cyst

Parathyroid cysts are rare lesions of uncertain embryological origin, usually presenting as a painless mass in the lower part of the neck. Clinical presentation usually mimics a thyroid nodule, and fine needle aspiration with demonstration of high parathyroid hormone levels in fluid is often required to establish the diagnosis. In addition to difficulty in diagnosis, the best treatment for these uncommon lesions remains controversial. We present a case of recurrent parathyroid cyst after several fine needle aspirations managed by surgery, and discuss the relevant associated literature.
