腱鞘滑膜结核与腱鞘滑膜瘤都发生在腱鞘滑膜上,好发于手部。由于早期症状不明显,所以容易误诊,或把二者相混淆。实际上滑膜结核与滑膜瘤的病因及病理变化不同,所产生的症状也不同,治疗方法也不一样。滑膜来自中胚叶,是一种特殊变化了的结缔组织,细胞呈梭形或圆形,在其特定条件下可转化为软骨细胞或骨细胞。腱鞘滑膜象衬里一样分布于腱鞘内,分为壁层和脏层,壁层衬在腱鞘内壁,脏层包绕着肌腱。二层之间有滑液分泌,滑膜于交接处形成腱纽,并代有供给肌腱营养的血管,从而保证肌腱在腱鞘内滑动及正常的新陈代谢。腱鞘滑膜结核:是由结核菌侵入滑膜,并在其中繁殖生长所致,多发于中年人,以血源性感染的 Tendon sheath synovial tuberculosis and tendon sheath synovial tumors occur in the tendon sheath, occur in the hand. As the early symptoms are not obvious, so easy to misdiagnosis, or confuse the two. In fact synovial tuberculosis and synovial tumor etiology and pathological changes are different, the symptoms are different, the treatment is not the same. Synovial membrane from the mesoderm, is a special change in the connective tissue, spindle or round cells, under its specific conditions can be transformed into chondrocytes or bone cells. Tendon sheath synovial lining as the same distribution within the tendon sheath, divided into the parietal and visceral, lining the lining of the inner wall of the tendon sheath, visceral layer around the tendon. Between the two layers of synovial fluid secretion, synovial junction of the formation of tendon New Zealand, and on behalf of the supply of blood vessels tendon nutrition, so as to ensure the tendon in the tendon sheath sliding and normal metabolism. Tendon sheath synovial tuberculosis: tuberculosis is invaded by the synovial membrane, and in which reproductive growth, mainly in middle-aged, with blood-borne infections
