Abnormal nodes can become fixed or matted to adjacent tissues, or to other nodes by invasive cancers. Mobility: normal lymph nodes are freely moveable in the subcutaneous space. Tender nodes suggest an inflammatory etiology. In general, firm nodes are more commonly seen in malignancy. 2000 Jul 75(7):723-32.Ĭonsistency: assessment of lymph node consistency is not a reliable measure to distinguish between malignant and benign etiologies. If there are no signs of systemic disease, lymph nodes measuring less than 1 cm can generally be observed. Lymph nodes greater than 2 cm that are persistent for more than 4 weeks should be evaluated. Abnormal lymph nodes are generally larger than 1 cm in diameter (however, inguinal lymph nodes may be as large as 2 cm in healthy individuals). Size: the significance of enlarged lymph nodes must be viewed in the context of their location, duration, associated symptoms, and patient age. Examining symmetry of lymph nodes from left and right sides of the patient can be helpful in distinguishing enlarged nodes. The most important physical exam findings are lymph node size, consistency, mobility, and distribution. Medication history: drug hypersensitivity (e.g., to phenytoin) is a common cause of lymphadenopathyĭuration of lymphadenopathy: persistent lymphadenopathy (more than 4 weeks) is indicative of chronic infection, collagen vascular disease, or underlying malignancy, whereas localized lymphadenopathy of brief duration often accompanies some infections (e.g., infectious mononucleosis or bacterial pharyngitis). 1990 Dec 17(6):696-703.Įpidemiologic clues: exposure to pets, occupational exposures, recent travel, or high-risk behaviors (intravenous drug use, unprotected sexual intercourse) may suggest specific disorders Symptoms of metastatic cancer: constitutional symptoms of malignancy such as unintentional weight loss may be associated with localized symptoms such as difficulty swallowing, hoarseness and pain (in head and neck cancer), cough, and hemoptysis (in lung cancer)Ĭonstitutional or 'B symptoms': fever (>100.4✯ ), night sweats, and/or unexplained weight loss greater than 10% of bodyweight over 6 months are concerning for malignancy, specifically a lymphoma arthralgias, rash, and myalgias suggest the presence of an autoimmune disorder Lister TA, Crowther D.

Symptoms of infection: these include pharyngitis, conjunctivitis, skin ulceration, localized tenderness, genital sores or discharge, fever, and night sweats Lymph node enlargement and risk of haematological and solid cancer. Frederiksen H, Svaerke C, Thomsen RW, et al. Among patients aged >65 years who present with enlarged lymph nodes, the risk of cancer is 28% within 1 year, rising to 42% within 10 years. Rapid access clinic for unexplained lymphadenopathy and suspected malignancy: prospective analysis of 1000 patients. Cancers are identified in approximately 14% of patients who present with unexplained lymphadenopathy.

The key aspects of the patient's history that aid in the diagnostic workup, and in the differential diagnosis, are:Īge of the patient: a malignant etiology is more likely in older patients. When the history and physical signs are diagnostic for a specific disorder, such as a localized skin infection or pharyngitis, no further testing is indicated and appropriate treatment should be initiated. Lymphadenopathy in a family practice: a descriptive study of 249 cases. Emerging and re-emerging infectious disease in otorhinolaryngology. Scasso F, Ferrari G, DE Vincentiis GC, et al.

Approximately 75% of lymphadenopathies are reported to be localized, with the remaining 25% generalized (secondary to systemic disease). If lymphadenopathy is localized, examine the regions drained by the nodes for evidence of infection, skin lesions, or neoplasms. In a patient presenting with lymphadenopathy, the history should focus on the extent of lymphadenopathy (localized versus generalized), recent infectious exposures, the presence or absence of constitutional symptoms, travel, high-risk behaviors (intravenous drug use, unprotected sexual intercourse), and potential associated medications.
