Lymph Node Regions in Head and Neck Definition Level I – Submental and submandibular Level II – Internal jugular chain, extends from the base of the skull to the bottom of the hyoid bone Level III – Internal jugular chain between the bottom of the hyoid bone and the bottom of the cricoi...
A lymph node is divided into an outer cortex and inner medulla and is surrounded by a fibrous capsule. The hilum is where blood vessels enter and exit the lymph node. The afferent lymphatic vessels bring lymph to the node through the cortex, while the efferent lymphatic vessel carries lymph ...
Axillary lymph nodes rarely have germinal centers at PND 42, possibly due to a lower level of antigenic stimulation of this “somatic” or peripheral lymph node as compared to the “enteric” lymph nodes (mandibular and mesenteric lymph nodes). Show moreView chapter Book 2016, Atlas of ...

Lymphatic node levels of the neck. Level I: submental and submandibular; level II: superior jugular; level III: middle jugular; level IV: inferior jugular; level V: supraclavicular or posterior; and level VI: central or anterior. Differential Diagnosis Most lymphadenopathy is benign in nature and...
We also discuss the definition of the superior mediastinal lymph nodes, which should not be mistaken for level VI. 展开 关键词: head and neck cancer lymph node classification level VI neck dissection diagnosis treatment esophagus thyroid larynx ...
BACKGROUND:In patients with nonsmall cell lung carcinoma (NSCLC) who have with pathologic N1 (pN1) lymph node status, the prognostic significance of segmental lymph node (level 13) metastasis and/or subsegmental lymph node (level 14) metastasis is unknown.METHODS:Lymph node metastasis patterns we...
The third pedicle arises from the posterior surface, courses posteriorly to the pre-sacral region and encounters the first lymph node usually at the level of second sacral foramina. Other lymphatics in this group proceed to the region of the sacral promontory. The fourth pedicle descends from ...
Meta-analysis plot for patients with Level II cervical LN metastasis. This is the forest plot generated from the 6 studies that contained relevant data. The 1st column specifies the study set used. The second column specified the proportion of patients that presented with lymph node metastasis in...
