MSN 610-module 2 -Lymph nodes
lymph general - answer lymph nodes lie is the subcutaneous connective tissues and
deepr nodes lie beneath the fascia of the muscle and within various body cavities nodes
are numerous and tiny but some of them ahve diameters large of 0.5 to 1 cm.
Readily accessible to inspection and palpations they provide some of the earliest clues
to the presence of infection or malignancies
Lymph drainage of lower Extremities - answer superior superficial inguinal nodes- deep
sublingual nodes- inferior superficial inguinal nodes-great saphenous lymphatic vessels
-popliteal nodes- small saphenous lymphatic vessels
lymph nodes in axillary vessels - answer subclavian-central axillary- brachial-
subscapular-external mammary-mammary
Lymphatic drainage of the female Gi tract - answer common iliac nodes-external iliac
nodes-deep inguinal nodes-superficial inguinal nodes- obturator nodes-internal iliac
nodes-preaortic nodes.
Lymph from the upper extremity to subclavian lymphatic trunk - answer brachial nodes-
epitrochlear nodes-radial lymphatic vessels- ulnar lymphatic vessels-median lymphatic
vessels
lymphatic drainage of breast - answer supraclavicular-subclavian-central axillary-
brachial-subscapular-external mammary-internal mammary-mammary
Lymph nodes involved with the ear - answer preauricular- parotid-internal jugular chain-
retropharyngeal-sternomastoid-posterior auricular
Lymph nodes involved with the tongue - answer submandibular-submental-sublingual-
suprahyoid- thyrolinguogacial- internal jugular chain
lymph nodes of the neck - answer submandibular- submental-suprahyoid-
thyrolinguofacial- anterior deep an superficial cervical-posterior superficial cervical -
anterior jugular- supraclavicular-posterior cervical spinal nerve chain-occipital-
retropharyngeal
lymph nodes most accessible to inspection/palpation - answer the necklace of nodes.
acute lymphangitis - answer inflammation one or more lymphatic vessel
p- pathogenic organism enter the lymphatic vessels directly through wounds as
complication of infection and produce a local inflammatory response.
s-enlarged lymph nodes, pain, fever, minor trauma to distal skin
, o- red streaks in the skin after course of lymphatic collecting ducts appear as tracing
rather fine lines streaking up the extremity. sometimes palpable to gentle touch,
acute suppurative lymphadenitis - answer infection of inflammation of lymph node may
affect a single or localized node
p-group a beta-hemolytic streptococci and coagulase positive staphylococcus infection.
lymph nodes enlarge due to because of cellular infiltration and edema.
s- enlarged lymph nodes, pain from enlarged lymph nodes
o-involved nodes usually firm in tender, overlying tissues add me to skin appears
erythematous usually within 72 hours, when abscesses form it is extensive nodes
fluctuant, micro bacterial adenitis characterized by inflammation without warmth that
may or may not slightly be tender.
lymphedema - answer edematous swelling due to excessive accumulation of lymph fluid
in tissues caused by inadequate lymph drainage
p- results of protein rich interstitial volume overload secondary to lymph drainage failure.
increase blood capillary hydrostatic pressure= decreased plasma protein concentration
increase blood permeability and blockage of lymph return
s-painless swelling of limb, onset gradual, hx of trauma surgery or radiation to regional
areas
o- falling and oftent grotesque distortion of extremities, lymphoedema may or may not
pit, overlying sing eventually thickens and feels though, primary lymphoedema often
apparent at birth.
Lymphangioma/cystic hygroma - answer congenital malformation of dilated lymphatics
p- results from failure of compete development and subsequent obstruction of lymphatic
system commonly found in the neck.
s- painless cystic masses usually manifest during the first year of life, often in large after
an upper respiratory infection. asymptomatic one in the posterior triangle of the neck.
o- soft nontender easily compressible spongy fluid containing mass without discrete
margins. most present at birth in neck. can distort face and neck.
lymphatic filariasis - answer massive accumulation of lymphedema throughout the body,
the most common cause of secondary lymphedema worldwide.
p- results from widespread inflammation and obstruction of lymphatics by the filaria
worm, transmitted by mosquitoes, adequate drainage is prevented and the patient
becomes more susceptible to infection. elephantids often incorrectly used
s- swelling in the limb or body area traveled to infected areas such as Asia Africa, India
an philippines. many asymptomatic but some may but some may develop fever with
lymphangitis and lymphadenitis chronci pulmonary infection in progressive
lymphoedema
o- lymphoedema of the entire arm or leg the genital regions, diagnosis can be made by
identification of microfile microscopically n the blood.
non-hodgkins lymphoma - answermalignant neoplasm of the lymphatic system and the
reticuloendothelial tissues
