[Parathyroid cyst. Report of ten cases]. / Les kystes parathyroïdiens. A propos de dix observations.

ABSTRACT

AIM OF THE STUDY To evaluate the characteristics of the parathyroid cysts (PC). PATIENTS AND METHOD: Ten patients with PC were included in this retrospective study. The PC were discovered as follows cervical mass (n = 3), hyperparathyroidism (n = 3), incidentally during thyroid surgery (n = 3) and screening for obesity (n = 1). Intracystic parathormone determination was performed after fine needle aspiration in 2 cases. RESULTS: Mean cyst measurements were 27 mm (ext 5-70 mm) to 22 mm (5-45 mm). Nine cysts were cervical (resection by cervicotomy), and one was mediastinal (resection by sternotomy). In addition to the resection of the PC, 3 adenomas, 1 hyperplasia of the parathyroid glands and 3 benign thyroid diseases were recognized and treated during the cervicotomies. CONCLUSION: The diagnosis of PC is not common and must be based primarily on the study of the cyst liquid obtained by percutaneous puncture (intracystic parathormone measurement).
