Lymphadenopathy
Lymphadenopathy: Excerpt from Professional Guide to Signs & Symptoms (Fifth Edition)
Lymphadenopathy—enlargement of one or more lymph nodes—may result from increased production of lymphocytes or reticuloendothelial cells, or from infiltration of cells that aren’t normally present. This sign may be generalized (involving three or more node groups) or localized. Generalized lymphadenopathy may be caused by an inflammatory process, such as bacterial or viral infection, connective tissue disease, an endocrine disorder, or neoplasm. Localized lymphadenopathy most commonly results from infection or trauma affecting a specific area. (See Areas of localized lymphadenopathy, page 492. See also Causes of localized lymphadenopathy, page 493.)
Normally, lymph nodes are discrete, mobile, soft, nontender and, except in children, nonpalpable. (However, palpable nodes may be normal in adults.) Nodes that are more than ⅜” (1 cm) in diameter are cause for concern. They may be tender and the skin overlying the lymph node may be erythematous, suggesting a draining lesion. Alternatively, they may be hard and fixed, tender or nontender, suggesting a malignant tumor.
History and physical examination
Ask the patient when he first noticed the swelling, and whether it’s located on one side of his body or both. Are the swollen areas sore, hard, or red? Ask the patient if he has recently had an infection or other health problem. Also ask if a biopsy has ever been done on any node because this may indicate a previously diagnosed cancer. Find out if the patient has a family history of cancer.
Palpate the entire lymph node system to determine the extent of lymphadenopathy and to detect any other areas of local enlargement. Use the pads of your index and middle fingers to move the skin over underlying tissues at the nodal area. If you detect enlarged nodes, note their size in centimeters and whether they’re fixed or mobile, tender or nontender, and erythematous or not. Note their texture: Is the node discrete, or does the area feel matted? If you detect tender, erythematous lymph nodes, check the area drained by that part of the lymph system for signs of infection, such as erythema and swelling. Also, palpate for and percuss the spleen.
Medical causes
Acquired immunodeficiency syndrome
Besides lymphadenopathy, findings include a history of fatigue, night sweats, afternoon fevers, diarrhea, weight loss, and cough with several concurrent infections appearing soon afterward.
Anthrax (cutaneous)
Lymphadenopathy, malaise, headache and fever may develop along with a lesion that progresses into a painless, necrotic-centered ulcer.
Brucellosis
Generalized lymphadenopathy usually affects cervical and axillary lymph nodes, making them tender. This disease usually begins insidiously with easy fatigability, malaise, headache, backache, anorexia, weight loss, and arthralgias; it may also begin abruptly with chills, fever that usually rises in the morning and subsides during the day, and diaphoresis.
Chronic fatigue syndrome
Lymphadenopathy may occur with incapacitating fatigue, sore throat, low-grade fevers, myalgia, cognitive dysfunction, and sleep disturbances. The diagnosis is one of exclusion and the cause of this syndrome is unknown.
Cytomegalovirus infection
Generalized lymphadenopathy occurs in the immunocompromised patient and is accompanied by fever, malaise, rash, and hepatosplenomegaly.
Hodgkin’s disease
The extent of lymphadenopathy reflects the stage of malignancy—from stage I involvement of a single lymph node region to stage IV generalized lymphadenopathy. Common early signs and symptoms include pruritus and, in older patients, fatigue, weakness, night sweats, malaise, weight loss, and unexplained fever (usually to 101° F [38.3° C]). Also, if mediastinal lymph nodes enlarge, tracheal and esophageal pressure produces dyspnea and dysphagia.
Kawasaki syndrome
Cervical lymphadenopathy is a characteristic sign of this potentially life-threatening illness. Affected individuals present with high, spiking fever, along with other diagnostic signs including erythema, bilateral conjunctival injection, and swelling in the peripheral extremities. Kawasaki syndrome isn’t contagious, however the cause remains unknown and typically affects children under age 5. Prompt detection and treatment with I.V. gamma globulin is essential in preventing serious complications, such as coronary artery dilations and aneurysms.
Leptospirosis
Lymphadenopathy occurs infrequently in this rare disease. More common findings include sudden onset of fever and chills, malaise, myalgia, headache, nausea and vomiting, and abdominal pain.
Leukemia (acute lymphocytic)
Generalized lymphadenopathy is accompanied by fatigue, malaise, pallor, and low fever. The patient also experiences prolonged bleeding time, swollen gums, weight loss, bone or joint pain, and hepatosplenomegaly.
Leukemia (chronic lymphocytic)
Generalized lymphadenopathy appears early, along with fatigue, malaise, and fever. As the disease progresses, hepatosplenomegaly, severe fatigue, and weight loss occur. Other late findings include bone tenderness, edema, pallor, dyspnea, tachycardia, palpitations, bleeding, anemia, and macular or nodular lesions.
Lyme disease
Spread by the bite of certain ticks, Lyme disease begins with a skin lesion called erythema chronicum migrans. As the disease progresses, the patient may suffer from lymphadenopathy, constant malaise and fatigue, and intermittent headache, fever, chills, and aches. He may go on to develop arthralgias and, eventually, neurologic and cardiac abnormalities.
Monkeypox
Lymphadenopathy is the one symptom that clearly distinguishes monkeypox from smallpox. Humans infected with monkeypox usually develop cervical or inguinal lymphadenopathy, along with other characteristic symptoms such as fever, chills, throat pain, muscle aches, and rash. This rare viral disease acquired its name after being discovered in laboratory monkeys; however, many other animals can carry this disease. Although the monkeypox virus is similar to smallpox, the smallpox vaccine is only used in limited circumstances to protect certain at-risk individuals against the disease.
Mononucleosis (infectious)
Characteristic, painful lymphadenopathy involves cervical, axillary, and inguinal nodes. Posterior cervical adenopathy is also common. Prodromal symptoms, such as malaise, fatigue, and headache, typically occur 3 to 5 days before the appearance of the classic triad of lymphadenopathy, sore throat, and temperature fluctuations with an evening peak of about 102° F (38.9° C). Hepatosplenomegaly may develop, along with findings of stomatitis, exudative tonsillitis, or pharyngitis.
Mycosis fungoides
Lymphadenopathy occurs in stage III of this rare, chronic malignant lymphoma and is accompanied by ulcerated brownish red tumors that are painful and itchy.
Non-Hodgkin’s lymphoma
Painless enlargement of one or more peripheral lymph nodes is the most common sign of this disease, with generalized lymphadenopathy characterizing stage IV. Dyspnea, cough, and hepatosplenomegaly occur, along with systemic complaints of fever to 101° F (38.3° C), night sweats, fatigue, malaise, and weight loss.
Plague
(Yersinia pestis). Signs and symptoms of the bubonic form of this bacterial infection include lymphadenopathy, fever, and chills.
Rheumatoid arthritis
Lymphadenopathy is an early, nonspecific finding associated with fatigue, malaise, continuous low fever, weight loss, and vague arthralgias and myalgias. Later, the patient develops joint tenderness, swelling, and warmth; joint stiffness after inactivity (especially in the morning); and subcutaneous nodules on the elbows. Eventually joint deformity, muscle weakness, and atrophy may occur.
Sarcoidosis
Generalized, bilateral hilar and right paratracheal forms of lymphadenopathy (seen on chest X-ray) with splenomegaly are common. Initial findings are arthralgia, fatigue, malaise, weight loss, and pulmonary symptoms. Other findings vary with the site and extent of fibrosis. Typical cardiopulmonary findings include breathlessness, cough, substernal chest pain, and arrhythmias. About 90% of patients have an abnormal chest X-ray at sometime during their illness. Musculoskeletal and cutaneous features may include muscle weakness and pain, phalangeal and nasal mucosal lesions, and subcutaneous skin nodules. Common ophthalmic findings include eye pain, photophobia, and nonreactive pupils. Central nervous system involvement may produce cranial or peripheral nerve palsies and seizures.
Sjögren’s syndrome
Lymphadenopathy of the parotid and submaxillary nodes may occur in this rare disorder. Assessment reveals cardinal signs of dry mouth, eyes, and mucous membranes, which may be accompanied by photosensitivity, poor vision, eye fatigue, nasal crusting, and epistaxis.
Syphilis (primary)
Localized lymphadenopathy and a painless ulcer (canker) with an indurated border and relatively smooth base at the site of sexual exposure characterize this infection. The ulcer is usually single but more than one may be present.
Syphilis (secondary)
Generalized lymphadenopathy occurs in the second stage and may be accompanied by a macular, papular, pustular, or nodular rash on the arms, trunk, palms, soles, face, and scalp. A palmar rash is a significant diagnostic sign. Headache, malaise, anorexia, weight loss, nausea, vomiting, sore throat, and low fever may occur.
Systemic lupus erythematosus
Generalized lymphadenopathy typically accompanies the hallmark butterfly rash, photosensitivity, Raynaud’s phenomenon, and joint pain and stiffness. Pleuritic chest pain and cough may appear with systemic findings, such as fever, anorexia, and weight loss.
Tuberculous lymphadenitis
Lymphadenopathy may be generalized or restricted to superficial lymph nodes. Affected lymph nodes may become fluctuant and drain to surrounding tissue. They may be accompanied by fever, chills, weakness, and fatigue.
Waldenström’s macroglobulinemia
Lymphadenopathy may appear along with hepatosplenomegaly. Associated findings include retinal hemorrhage, pallor, and signs of heart failure, such as jugular vein distention and crackles. The patient shows decreased level of consciousness, abnormal reflexes, and signs of peripheral neuritis. Weakness, fatigue, weight loss, epistaxis, and GI bleeding may also occur. Circulatory impairment occurs because of an increased viscosity of the blood.
Other causes
Drugs
Phenytoin may cause generalized lymphadenopathy.
Immunizations
Typhoid vaccination may cause generalized lymphadenopathy.
Special considerations
If the patient has fever above 101° F (38.3° C), don’t automatically assume that the temperature should be lowered. A patient with a bacterial or viral infection must tolerate the fever, which may assist recovery. Provide an antipyretic if the patient is uncomfortable. Tepid sponge baths or a hypothermia blanket may also be used.
Expect to obtain blood for routine blood work, platelet and white blood cell counts, liver and renal function studies, erythrocyte sedimentation rate, and blood cultures. Prepare the patient for other scheduled diagnostic tests, such as chest X-ray, liver and spleen scan, lymph node biopsy, or lymphography, to visualize the lymphatic system. If tests reveal infection, check your facility’s policy regarding infection control.
Pediatric pointers
Infection is the most common cause of lymphadenopathy in children. The condition is commonly associated with otitis media and pharyngitis.
Provide an antipyretic if the child has a history of febrile seizures.
