AB Normal  lymph  nodes  in  the  neck  are  usually  less  than  1  cm  in  length.  Infections  involving  the  pharynx,  salivary  glands,  and  scalp  often  cause  tender  enlargement  of  neck  nodes.  Enlarged  nodes  are  common  in  HIV-infected  persons.  Except  for  the  occasional  node  that  suppurates  and  requires  incision  and  drainage,  treatment  is  directed  against  the  underlying  infection.  An  enlarged  node  (larger  than  1.5  cm)  or  node  with  a  necrotic  center  that  is  not  associated  with  an  obvious  infection  should  be  further  evaluated,  especially  if  the  patient  has  a  history  of  smoking,  alcohol  use,  or  prior  cancer.  Other  common  indications  for  FNA  biopsy  of  a  node  include  its  persistence  or  continued  enlargement.  Common  causes  of  cervical  adenopathy  include  cancer  (eg,  squamous  cell  carcinoma,  lymphoma,  occasional  metastases  from  non-head  and  neck  sites)  and  infection  (eg,  reactive  nodes,  mycobacteria,  and  cat-scratch  disease).  Rare  causes  of  adenopathy  include  Kikuchi  disease  (histiocytic  necrotizing  lymphadenitis)  and  autoimmune  adenopathy.
