Lymphatic Drainage Flashcards
Ovaries
Para-aortic lymphatics via the gonadal vessels
Uterine fundus
Runs with the ovarian vessels and may thus drain to the para-aortic nodes. Some drainage may also pass along the round ligament to the inguinal nodes.
Body of the uterus
Drains through lymphatics contained within the broad ligament to the iliac lymph nodes
Cervix
Drains into three potential nodal stations:
- laterally through the broad ligament to the external iliac nodes
- along the lymphatics of the uterosacral fold to the presacral nodes
- posterolaterally along lymphatics lying alongside the uterine vessels to the internal iliac nodes
Anterior two thirds of the tongue
Minimal communication of lymphatics across the midline, so metastasis to the ipsilateral nodes is usual
Posterior third of the tongue
Communicating networks, as a result early bilateral nodal metastases are more common in this area
Tip of the tongue
Pass to the sub mental nodes and from there to the deep cervical nodes
Mid portion of the tongue
Drain to the submandibular nodes and then to the deep cervical nodes. Mid tongue tumours that are laterally located will usually drain to the ipsilateral deep cervical nodes, those from more central regions may have bilateral deep cervical nodal involvement.
Superior aspect of the vagina
The internal and external iliac nodes
Inferior aspect of the vagina
Superficial inguinal nodes
Lateral surface of the upper half of the auricle
Drains to the superficial parotid lymph nodes
Cranial surface of the superior half of the auricle
Drains to the mastoid nodes and deep cervical lymph nodes
Lower half of the auricle and lobule
Drain into the superficial cervical lymph nodes
Vocal cords
No lymphatic drainage and this site acts as a lymphatic watershed
Supraglottic part of the larynx
Upper deep cervical nodes
Subglottic part of the larynx
Prelaryngeal and pretracheal nodes and inferior deep cervical nodes
Aryepiglottic fold and vestibular folds
Dense plexus of lymphatics associated with them and malignancies at these sites have a greater propensity for nodal metastasis
Upper third of the oesophagus
Deep cervical lymph nodes
Mid third of the oesophagus
Mediastinal lymph nodes
Lower third of the oesophagus
Gastric lymph nodes
Breast
70% Axillary nodes
Internal mammary chain
Other lymphatic sites such as deep cervical and supraclavicular fossa (later in disease)
Left side of the head and neck
Lymphatics join the thoracic duct prior to its insertion into the left brachiocephalic vein
Right side of the head and neck
Lymphatics drain via the subclavian and jugular trunks into the right lymphatic duct and thence into the mediastinal trunk and eventually the right brachiocephalic vein
Scrotum
Inguinal lymph nodes
