Brown tumor of the knee is a focal benign cystic lesion of bone. The etiopathogenesis of brown tumor is believed to be abnormal bone metabolism in patients with hyperparathyroidism. We present a case of a 32-year-old male with recurrent knee pain, weakness of the lower limb and a nodular mass on left inferior lobe of thyroid. Timely identification of the underlying cause and localization of lesion(s) is important because the management and prognosis vary based on the etiology. The diagnosis of a brown tumor is the result of the sum of the medical history of patients with clinical, radiographic imaging, histopathological, hematological, and biochemical laboratory investigations.
膝关节棕色瘤是一种局限性骨良性囊性病变。棕色瘤的发病机制被认为是甲状旁腺功能亢进患者的骨代谢异常。我们报告一例32岁男性患者，有反复膝关节疼痛、下肢无力以及甲状腺左叶下极有一个结节状肿块。及时识别潜在病因和病变定位很重要，因为治疗和预后因病因不同而有所差异。棕色瘤的诊断是患者病史、临床检查、影像学检查、组织病理学检查、血液学检查和生化实验室检查结果综合判断的结果。
