title: [Nonfunctioning parathyroid cyst simulating thyroid nodule].
abstract: A parathyroid cyst is a rare disease. A 48 year old man with a nonfunctioning parathyroid cyst is described. The cyst was initially misdiagnosed and taken for a thyroid cyst based on physical examination, thyroid scan, sonography and needle biopsy. Cervical exploration was performed due to the recurrence of the lesion. The cyst was resected and histology showed it to be a parathyroid cyst. Pre and post operative clinical aspects are discussed.
