asymmetric shotty supraclavicular lymph nodes

18 If a reactive lymph node is likely, core needle biopsy can be avoided, and FNA used alone. FNA cytology is a quick, accurate, minimally invasive, and safe technique to evaluate patients and aid in triage of unexplained lymphadenopathy. Rheumatoid arthritis, Sjögren syndrome, dermatomyositis, systemic lupus erythematosusĪntinuclear antibody, anti-doubled-stranded DNA, erythrocyte sedimentation rate, CBC, rheumatoid factor, creatine kinase, electromyography, or muscle biopsy as indicatedįine-needle aspiration (FNA) and core needle biopsy can aid in the diagnostic evaluation of lymph nodes when etiology is unknown or malignant risk factors are present ( Table 4 4, 6, 10 ).

Biopsy options include fine-needle aspiration, core needle biopsy, or open excisional biopsy. The workup may include blood tests, imaging, and biopsy depending on clinical presentation, location of the lymphadenopathy, and underlying risk factors. Palpable supraclavicular, popliteal, and iliac nodes are abnormal, as are epitrochlear nodes greater than 5 mm in diameter. Risk factors for malignancy include age older than 40 years, male sex, white race, supraclavicular location of the nodes, and presence of systemic symptoms such as fever, night sweats, and unexplained weight loss. Generalized lymphadenopathy, defined as two or more involved regions, often indicates underlying systemic disease.

Patients with localized lymphadenopathy should be evaluated for etiologies typically associated with the region involved according to lymphatic drainage patterns. When the cause is unknown, lymphadenopathy should be classified as localized or generalized. The history and physical examination alone usually identify the cause of lymphadenopathy. Etiologies include malignancy, infection, and autoimmune disorders, as well as medications and iatrogenic causes. Lymphadenopathy is benign and self-limited in most patients.
