锁骨上淋巴结属于颈深淋巴结的下组,当患有胃癌或食管癌时癌细胞早期即可经胸导管转移至左锁骨上淋巴结.因此,左锁骨上淋巴结的活检对早期诊断恶性肿瘤并追查原发病灶有一定的临床价值.目前,锁骨上淋巴结的配布描述亦尚未统一1 材料用50具(男45.女5)成人标本上对锁骨上淋巴结进行了解剖和观察.2 结果2.1 锁骨上淋巴结的形态 观察50例标本,左侧共有淋巴结194个,平均为3.90±1.40个(1～8个),其中圆形淋巴结为64个(33%)、椭圆形130个(67%);圆形淋巴结直径为5.30±1.60mm(2～9mm).椭圆形淋巴结长径为8.70±2.90mm(3～19mm),宽径为5.60±2.00mm(2～12mm)右侧共有淋巴结165个,平均为3.70±1.25个(1～6个),其中圆形淋巴结58个(35%).椭圆形107个(65%).圆形淋巴结的直径为4.74±1.62mm(2～9mm),椭圆形淋巴结的长径为7.92±2.87mm(3～18mm).宽径为5.06±1.93mm(1～10mm)2.2 锁骨上淋巴结的分布 以肩胛舌骨肌下腹为
Supraclavicular lymph nodes belong to the lower cervical lymph node group, when suffering from gastric cancer or esophageal cancer cells can be transferred to the left supraclavicular lymph node early lymph node.Therefore, the left supraclavicular lymph node biopsy early diagnosis of malignant tumor and trace the original The lesions have a certain clinical value.Currently, supraclavicular lymph node distribution has not yet described a unified material with 50 (male 45 female 5) adult specimens of the supraclavicular lymph nodes were dissected and observed.2 results 2.1 supraclavicular lymph nodes The morphology of the specimens was observed in 50 cases. There were 194 lymph nodes on the left, with an average of 3.90 ± 1.40 (1 ~ 8), of which 64 (33%) were round and 130 (67% The diameter of lymph nodes was 5.30 ± 1.60mm (2 ~ 9mm) .The long diameter of oval lymph nodes was 8.70 ± 2.90mm (3 ~ 19mm) and the width of the right common lymph nodes was 5.60 ± 2.00mm (2 ~ 12mm) 3.70 ± 1.25 (1 ~ 6), of which, there were 58 (35%) round lymph nodes and 107 (65%) elliptical ones.The diameter of round lymph nodes was 4.74 ± 1.62mm (2 ~ 9mm) The long diameter of 7.92 ± 2.87mm (3 ~ 18mm). Wide diameter of 5.06 ± 1.93mm (1 ~ 10mm) 2.2 The distribution of supraclavicular lymph nodes in the scapular hyoid muscle Belly is
