CONTEXT
Parathyroid cysts are rare clinical and pathological entities, with less than 300 cases reported. The inferior parathyroid glands are most commonly involved, with left-side predominance. Parathyroid cysts may be functional or nonfunctional, depending on their association with hypercalcemia.
CASE REPORT
A 25-year-old man presented a palpable asymptomatic left-side neck mass. Ultrasound revealed a cystic structure contiguous with the left thyroid lobe. Serum ionic calcium was normal. The patient underwent left thyroid lobectomy plus isthmectomy with excision of the cyst. The histological findings revealed a parathyroid cyst. Parathyroid cysts typically present as asymptomatic neck masses, and surgical excision appears to be the treatment of choice.
背景
甲状旁腺囊肿是罕见的临床和病理实体，报告病例少于300例。下甲状旁腺最常受累，以左侧为主。甲状旁腺囊肿可能是功能性的或无功能性的，这取决于它们与高钙血症的关联。
病例报告
一名25岁男性出现左侧颈部可触及的无症状肿块。超声显示与左甲状腺叶相邻的囊性结构。血清离子钙正常。患者接受了左甲状腺叶切除术加峡部切除术并切除囊肿。组织学检查结果显示为甲状旁腺囊肿。甲状旁腺囊肿通常表现为无症状的颈部肿块，手术切除似乎是首选治疗方法。
