Introduction: Parathyroid cysts are a rare clinical and histological entity; they represent 0.5% of parathyroid pathology and 1% of cervical cystic masses. They are rarely revealed by a palpable cervical swelling and are often an operative discovery. They can be non-functional or responsible for hyperparathyroidism. The aim of this work is to specify the clinical, paraclinical and therapeutic profile of these cysts

Material and methods: Our work is a retrospective study of 10 cases of parathyroid cyst discovered peroperatively collected in the ENT and CCF department.

Results: Our series has collected 10 cases of parathyroid cyst. There were 10 women, with an average age of 50 years. The reason for consultation was paramedian cervical swelling in all cases. The cervical ultrasound performed in all cases was in favor of a thyroid nodule in most cases. The biological assessment was normal. Fine needle aspiration cytology was not performed given the significant size of the swellings (> 3 cm) leading to the indication of surgery. The diagnosis was made intraoperatively. The anatomopathological examination confirmed the diagnosis of parathyroid cyst.

Conclusion: Parathyroid cyst is rarely considered in the presence of cervical swelling. They are generally discovered intraoperatively, however the diagnosis can be made by measuring parathyroid hormone in the puncture fluid. The treatment is surgical. Monitoring of calcemia postoperatively is necessary.
