“…The exact incidence is still discussed, given that in one study its occurrence ranged from 0.08 to 3.4% of the cases of thyroid or parathyroid resection 4 . In a study with thyroid and parathyroid specimens examined within a period of 15 years, parathyroid cysts were found in 0.6% 3 . Analyses in autopsies revealed 40 to 50% of parathyroid glands that contained asymptomatic microcysts 5 , given that in only 1 to 3% they presented as a neck mass 6 .…”

“…Parathyroid cysts are pathologies considered to be rare, comprising about 250 cases described in the literature 1,2,3 . The exact incidence is still discussed, given that in one study its occurrence ranged from 0.08 to 3.4% of the cases of thyroid or parathyroid resection 4 .…”

“…Pathogenesis of parathyroid cyst is uncertain, and there are some theories that explain its origin: (1) as embryological remains of 3rd and 4th branchial arches, causing increase in volume by accumulation of secretion forming a macrocyst; (2) degeneration, infarction or hemorrhage of parathyroid or gland adenoma; (3) coalescence of microcysts of normal or adenomatous parathyroid aspect; (4) persistence of Kustneiner canal, which are vesicular canals in fetus or gland remains, and (5) retention of parathyroid hormone (PTH) in colloid vesicles 8 . Despite these embryological theories, there are no reports of parathyroid cysts in children 1,3,8,9 . Parathyroid cysts may be classified as functioning and nonfunctioning depending on the association with hyperparathyroidism.…”

“…In most cases reported in the literature, less than 10% are functioning; differently from Calandra et al 8 in which 10 out of 11 patients with parathyroid cysts had parathyroidism, evidencing hypercalcemia, hypophosphatemia and increase of serum PTH. Patients with functioning cysts tend to be men, being 1.6 times more frequent than in women and of older age 1,3 . Nonfunctioning cysts are described as the most common, predominantly in women.…”

Parat hyroid cysts are rare lesions, usually located in the neck and mediastinum in about 10% of the cases, predominantly in women. The majority of the lesions are nonfunctioning; however, functioning cysts are associated with hyperparathyroidism. The diagnosis of parathyroid cyst is difficult, and frequently misdiagnosed as thyroid pathology and the final diagnosis is made during surgery confirmed by histopathological examination. A crystal clear fluid and elevated PTH levels in cyst fluid confirm the diagnosis.

“…PCs may be functional or non-functional, depending on the ability of the cyst to secrete parathyroid hormone (PTH). In total, 15-57% of PCs are functional (5)(6)(7). In addition, the majority of non-functional PC lesions are small in size and are occasionally revealed during imaging procedures or cervical surgery, with only a minority characterized by a large size and compressive symptoms (8).…”

Abstract. Giant parathyroid cysts (PCs) are a rare entity and possess a benign clinical course. PCs may be functional or non-functional, depending on the ability of the cyst to secrete parathyroid hormone (PTH). The present study reports a rare case of a giant PC in a 56-year-old male who presented to the Affiliated Tumor Hospital, Zhengzhou University (Zhengzhou, Henan, China) with a 10-month history of exertional dyspnea, associated with mild dysphagia that had persisted for 3 months. The present study reviews the clinical situation, laboratory examination, radiographic findings, treatment and prognosis of the patient, and provides a brief discussion regarding the associated literature. Giant PCs may manifest with compressive symptoms of the surrounding tissues. The diagnosis of a giant PC is based on increased levels of PTH in the fluid collected during the aspiration of the cyst. Management by surgical excision is recommended for giant PCs that cause local cervical symptoms.

Cystic parathyroid lesions often contain turbid or colored fluid, and FPCs are more common than NPCs. Neck cysts of uncertain origin should be diagnostically aspirated for parathyroid hormone content. During resection, cyst rupture should be avoided, and patients with large cysts should be managed expectantly to forestall the development of symptomatic hypocalcemia. Functional parathyroid cysts and NPCs are likely 2 separate clinical and histologic entities.
