Role of FNAC in the diagnosis of lymph node malignancies in the head and neck region.
Background: Enlarged lymph nodes are easily accessible for FNA and hence FNAC is a very simple and diagnostic tool for lymph node lesions. FNAC is rapidly emerging as a useful tool in the diagnosis of metastatic lesions of lymph nodes. Aims: The present study aimed at studying the role of FNAC in diagnosing lymph node malignancies. Methods: The study was conducted over a period of one year from November 2014 to October 2015. A total of 441 aspirations were performed on enlarged lymph nodes in the head and neck region. The cytological diagnosis was correlated with histopathological diagnosis wherever available. Results: Of the 441 aspirations performed on lymph nodes in the head and neck region, 81(18.37 %) were diagnosed with lymph node malignancies. Of 81 cytologically diagnosed cases, Histopathological correlation was available in 52 cases which were included in the study. The age group ranged from 8 to 82 years with males being more involved (78% cases). The overall diagnostic accuracy in diagnosing lymph node malignancies in our study came out to be 98.08% % and sensitivity was 100%. The cervical group of lymphnode is the most common group to be involved by malignancy and Squamous cell carcinoma being the most common histologic type.
