【 摘 要 】
Functional parathyroid cysts are a rare cause of primary hyperparathyroidism and are often mistaken for thyroid cysts.Systemic lupus erythematosus (SLE) is also a very rare cause of hypercalcemia. We report the case of a 62-year-old woman,who was diagnosed with SLE 30 years ago, presenting with clinical and biochemical features of primary hyperparathyroidism.Laboratory investigation revealed increased serum calcium and parathyroid hormone (PTH) levels; neck ultrasonography(USG) revealed 40!34!26 mm cystic mass in the left lobe of thyroid gland. PTH level in the cysts was O2500 pg/ml,determined by USG-guided fine-needle aspiration (FNA). In this case, no evidence for potential pathogenic associationbetween parathyroid cyst and SLE was uncovered. However, the recognition of this association is very important because thetherapeutical strategy is completely different. Operative management is usually straightforward and alleviates symptomsand any biochemical abnormalities caused by the cyst.
