PY - 2014 T2 - Strange and Schafermeyer's Pediatric Emergency Medicine, 4e AB - Most common neck masses in children are benign reactive lymphadenopathy and lymphadenitis.Congenital neck lesions can present even after the first decade of life often with an infection or obstruction.Occasionally, a neck mass may be related to a systemic illness or sign of a neoplastic condition and further investigation is warranted particularly if there is supraclavicular lymphadenopathy.Neck masses that affect the airway require immediate intervention.Laboratory testing is often not necessary in the evaluation of cervical lymphadenopathy as the cause can usually be determined by the history and physical examination.An enlarged cervical mass that does not improve after 4 to 6 weeks needs to be referred to a subspecialist for further evaluation.
