title: Value of immunohistochemistry in the diagnosis of malignant cervical lymph nodes.
abstract: The cervical lymph nodes are relevant due to the diversity of clinical entities. The use of immunohistochemistry is a real method to elucidate the diagnosis of adenopathy, both primary and metastatic neoplasms.
  
  
  OBJECTIVE
  To assess the value of immunohistochemistry in the diagnosis of cervical lymph nodes malignancies.
  
  
  METHODS
  Retrospective study of the database histopathological specimens from 2009 to 2011.
  
  
  RESULTS
  Out of 32 biopsies of cervical lymph nodes, in 16 (50%) the immunohistochemistry was employed, being 68.75% (11) in hematological neoplasms and 31.25% (5) in carcinomas. It was used in all cases of lymphoma.
  
  
  CONCLUSIONS
  The immunohistochemistry was used in 50% of the biopsies of lymph nodes under suspicion of malignancy, being 31.25% in epithelial lesions and 68.75% in lymphoproliferative lesions.
