You are seeing C.S., a 7 year old female who was brought to clinic by her mother to evaluate a
painful red swelling in her right axilla. You enter the room with your preceptor and complete a
brief history and exam together. She has had intermittent fever and malaise that improves with
ibuprofen. She is one of four children and no other siblings are ill, and her mother reports no
unusual activities. Vital signs are: Pulse - 76, respirations 16, blood pressure 112/65,
temperature 99oF. On exam she appears nontoxic but is reluctant to let you palpate her axilla;
lymphatic exam is notable for tender, slightly fluctuant adenopathy and overlying erythema in
the right axilla and palpable epitrochlear nodes on the right. HEENT is benign, chest is clear and
heart and abdomen are benign.
Your preceptor asks you to perform a more detailed history and exam while they go see another
patient. Based on this presentation, of the ch - ANSB. Have you or C.S. noticed any sores,
scratches, or injuries on her arms or hands or other extremities in the past few weeks?
The enlargement and inflammation in axillary and epitrochlear nodes suggests response to a
localized infection or injury of the right upper extremity. While a thorough history is always
helpful, the most important questions questions would relate to eliciting a history of skin
infections, abrasion, scratches, or other injury.
You elicit a history that C.S. was playing with new kittens while visiting her grandparents two
weeks ago. Based on this additional information, which of the following is the most likely cause
of her symptoms?
A. Filariasis
B. Bartonella henselae
C. Pasturella multocida
,D. Afipia felis - ANSB. Bartonella henselae
Cat scratch disease usually presents as a localized, self-limited disorder affecting skin and
regional lymph nodes after inoculation, usually after a scratch or after being bitten by a flea from
an infected animal. In some cases, especially those with immune compromise, the organisms
may cause a life threatening disseminated infection. Bartonella henselae is the etiologic agent in
most cases of cat scratch disease; infected cats may not appear ill, and may carry the organism
within their erythrocytes for months or years. A. felis is an unusual cause of cat scratch disease.
Pasturella multocida is another important cause of infections related to cat bites and scratches
but results in cellulitis, soft tissue and other infections rather than lymphadenitis. Filariasis may
also cause acute lymphadenitis and lymphangitis but is a disease of tropical areas.
Which of the following is considered least appropriate when examining the lymphatic system?
A. Perform an exam of the entire lymphatic system as a whole, examining all chains
consecutively.
B. Use the pads of the second, third and fourth fingers to gently palpate for adenopathy.
C. Examine the lymphatic system region by region during your assessment of related body
regions or systems.
D. If you encounter enlarged lymph nodes, explore adjacent areas and systems drained by the
drainage systems related to those nodes. - ANSA. Perform an exam of the entire lymphatic
system as a whole, examining all chains consecutively.
The lymphatic system is best examined regionally as you assess the relevant body area or
organ system; for example during the HEENT exam you would evaluate the lymphatic chains of
the head and neck for abnormalities, but you would not examine inguinal nodes until
examination of the lower extremities and lower abdomen. The pads of the fingers should be
used for examination, pressing lightly at first and then palpating more deeply. When enlarged
nodes are encountered, look more carefully for possible causes that may have been missed
during the related screening exam, as enlarged lymph nodes may indicate regional pathology.
You are evaluating a 55 year old woman with longstanding swelling of both of her legs. You are
trying to decide whether to describe her condition as lymphedema or edema; which of the
following favors a diagnosis of lymphedema?
A. Leg swelling is not improved after spending the night in bed.
B. The skin is hard and thickened with areas of warty hypertrophy.
C. She has had the swelling since adolescence.
, D. Diuretics (medications that increase the amount of urine produced by the kidney and reduce
body water) have never helped with the edema.
E. All of the above - ANSE. All of the above
Lymphedema is related to disruption of lymphatic flow, and is different and more difficult to treat
compared to the edematous states caused by abnormal flow in the venous system.
Lymphedema may be caused by congenital abnormalities in lymphatic drainage (primary
lymphedema) or by secondary damage cause by cancer, trauma, or localized inflammation and
infection. In the developed world, the most common cause of lymphedema is cancer, related to
surgical excision and staging or malignant obstruction of normal lymphatic drainage. In third
world countries, parasitic infections, primarily filariasis, cause the condition. While diuretics and
mechanical measures like leg elevation can help edema caused by reduced venous return,
these rarely help the edema caused by obstruction of lymphatics.
Match the scenario with the underlying pathology.
48 year old smoker with hard 2.5 cm left supraclavicular node
A. Thoracic malignancy
B. Staphylococcal cellulitis of the leg
C. Infectious Mononucleosis
D. Benign developmental finding
E. Lymphoma - ANSA. Thoracic malignancy
Because of its role in the immune systems, abnormalities in the lymphatic system can be among
the earliest markers of disease, especially infection and malignancy. Characteristics of the
patient and nodes suggest underlying pathology. Nodes that are larger than 1 cm are
considered abnormal, with the exception of inguinal nodes which may be considered within
normal limits up to a diameter of 2 cm. Nodes that are matted, hard, or rubbery are concerning
for malignancy, and nodes that are tender or fluctuant are concerning for malignancy; likewise
rapid growth of a node raises concern where as a node that has remained stable in size for
years is less likely to signal pathology. Supraclavicular nodes are nearly always pathologic.
