When assessing the aetiology, take into account possible symptoms of infection, the patient’s age and the location of the lump.
After acute infection, the lymph nodes in the neck often are bilaterally enlarged. This article deals with situations where the lump has not receded in 2 to 4 weeks or is not clearly associated with other local infection.
Also normal lymph nodes (< 1 cm) are often palpable. Even slightly lager symmetrically palpable lymph nodes at the mandibular angles are common and rarely require further investigations.
