    Study Notes

    Understanding Lymphadenopathy

    • Lymphadenopathy can be caused by various conditions such as infections, inflammations, medications, and malignancies.
    • Symptoms of lymphadenopathy may include swollen, hard, tender, or draining lymph glands, as well as associated symptoms like fevers, rashes, fatigue, and unintentional weight loss.
    • It is important to consider a wide range of potential causes such as bacterial or viral infections, sexually transmitted diseases, autoimmune disorders, and malignancies like breast cancer, lung cancer, or melanoma.
    • Diagnostic approach for lymphadenopathy includes considering the patient's medical history and conducting a thorough physical examination, as well as using diagnostic algorithms and considering alarm symptoms suggestive of malignancy.
    • It is essential to be cautious and consider other conditions that may mimic lymph node swelling, such as lipomas, sebaceous cysts, abscesses, or thyroid nodules.
    • Nonspecific lymphadenopathy that persists or progresses should prompt repeated evaluation, patient education, and shared decision making regarding further diagnostic work-up options.
    • The prognosis for lymphadenopathy in primary care settings is generally good, especially in younger patients, justifying reassurance and observation when the cause appears to be benign or self-limited.
    • Inflammatory causes, bacterial or mycobacterial infections, metastatic cancer, and medication-associated serum sickness are some of the potential causes of lymphadenopathy.
    • Lymphadenopathy can be associated with specific symptoms, such as genital herpes, sporotrichosis, herpes zoster, mumps, and joint pain, mouth ulcers, rashes after sun exposure, dry mouth, or dry eyes.
    • Understanding the time course and modifying symptoms of lymphadenopathy, such as changes over time and factors that make it better or worse, is important for diagnosis and management.
    • The text includes a diagnostic algorithm for lymphadenopathy, which involves considering sexually transmitted diseases, connective tissue diseases, tuberculosis, upper respiratory infections, and other alarm symptoms suggestive of malignancy.
    • It is important to address the emotional impact of lymph node swelling on patients and their families, and to provide reassurance and observation when the cause appears to be benign or self-limited.

    Lymphadenopathy and its Causes

    • Lymphadenopathy is typically caused by inflammatory or neoplastic cell infiltration, resident lymphocyte proliferation, or expansion due to hemorrhage or abscess formation.
    • In primary care settings, malignancy is rare, with over two-thirds of cases being due to upper respiratory tract infections or nonspecific conditions.
    • The risk of malignancy increases with age and other factors, but careful history taking is important in determining the cause of lymphadenopathy.
    • The medical interview can assist in excluding malignancy or other serious underlying diseases in most patients and inform subsequent evaluation for the remainder.
    • In primary care practice, over two-thirds of patients with lymphadenopathy have nonspecific causes or upper respiratory illnesses, with less than 1% having malignancy.
    • Of the patients with benign lymphadenopathy, 63% had a nonspecific or reactive etiology, and the remainder had a specific cause demonstrated, most commonly infectious mononucleosis, toxoplasmosis, or tuberculosis.
    • The major causes of lymphadenopathy in the United States are listed using the mnemonic CINEMA DIVITT (congenital, infectious, neoplastic, endocrine, metabolic, allergic, degenerative, inflammatory/immunologic, vascular, idiopathic or iatrogenic, traumatic, toxic) or MIAMI (malignancies, infections, autoimmune disorders, miscellaneous and unusual conditions, and iatrogenic causes).
    • Differential diagnosis for lymphadenopathy includes congenital syphilis, upper respiratory infections, bacterial and viral infections, fungi, parasites, rickettsiae, and neoplastic conditions.
    • Specific bacterial causes of lymphadenopathy include actinomycosis, brucellosis, cat-scratch disease, chancroid, and others.
    • Viral causes include adenovirus, cytomegalovirus, Epstein-Barr virus, hepatitis B and C, herpes simplex, human immunodeficiency virus, and others.
    • Parasitic causes include Chagas disease, filariasis, kala-azar, leishmaniasis, toxoplasmosis, and trypanosomiasis.
    • Neoplastic causes account for 0.8%-1% of cases of lymphadenopathy.

    Understanding Lymphadenopathy and Alarm Symptoms

    • Lymphadenopathy can have benign causes, but it can also be due to serious conditions such as cancer, systemic infection, and autoimmune connective tissue disease.
    • The relative prevalence of serious diagnoses in primary care settings includes cancer (1%-4%), local infections for which antimicrobial therapy may be beneficial (10%-30%), systemic infection (<1%), and severe autoimmune disease (<1%).
    • Alarm symptoms to consider include persistence or growth over several weeks or months, systemic inflammation/infection, and the description of a "hard" lymph node.
    • Specific locations of lymphadenopathy can indicate different conditions, such as right supraclavicular lymphadenopathy indicating metastatic cancer of the mediastinum, esophagus, or thorax.
    • Other conditions associated with lymphadenopathy include breast cancer, lymphoma, sarcoidosis, HIV infection, tuberculosis, and autoimmune diseases.
    • Medications and constitutional symptoms like malaise, fatigue, fever, unintentional weight loss, and night sweats can also be linked to lymphadenopathy.
    • Focused questions should be asked to determine the likely cause of lymph node enlargement, with particular attention to alarm symptoms that greatly influence subsequent diagnostic decision making.
    • Questions to consider include inquiries about cancer history, recent travel, family history of head and neck cancer, alcohol and tobacco use, radiation exposure, TB skin test, exposure to undercooked meats, and tick bites.
    • Other questions should cover exposure to infectious diseases, such as cat-scratch disease, toxoplasmosis, and HIV, as well as changes in moles and skin lesions.
    • Inquiring about specific exposures can help in identifying potential causes of lymphadenopathy, such as unpasteurized milk or cheese consumption, hunting and eating wild animals, and tick bites in Lyme disease-endemic areas.
    • Questions about risky behaviors, such as unprotected sexual intercourse and injection drug use, can also aid in diagnosing potential causes of lymphadenopathy, including HIV, hepatitis B and C, and syphilis.
    • Detailed questioning can help in identifying the underlying cause of lymphadenopathy and guide subsequent diagnostic and therapeutic decisions.
