摘 要:Hyperparathyroidism(HPT)is a condition in which one or more parathyroid glands produce increased levels of parathyroid hormone(PTH),causing disturbances in calcium homeostasis.Most commonly HPT presents with asymptomatic hypercalcemia but the clinical spectrum may include disturbances reflecting the combined effects of increased PTH secretion and hypercalcemia.Brown tumors are rare,benign,tumor-like bone lesions,occurring in 1.5%to 4.5%of patients with HPT,as a complication of an uncontrolled disease pathway,and are nowadays rarely seen in clinical practice.The tumor can appear either as a solitary or multifocal lesion and usually presents as an asymptomatic swelling or a painful exophytic mass.Furthermore,it can cause a pathological fracture or skeletal pain and be radiologically described as a lytic bone lesion.The diagnosis of a brown tumor in HPT is typically confirmed by assessing the levels of serum calcium,phosphorus,and PTH.Although when present,brown tumor is quite pathognomonic for HPT,the histologic finding often suggests a giant cell tumor,while clinical presentation might suggest other more frequent pathologies such as metastatic tumors.Treatment of brown tumors frequently focuses on managing the underlying HPT,which can often lead to regression and resolution of the lesion,without the need for surgical intervention.However,in refractory cases or when dealing with large symptomatic lesions,surgical treatment may be necessary.
