Fine needle aspiration cytology for non-thyroidal neck masses has equal diagnostic yield to
The findings were TB 31%, metastatic lymph node 19%, reactive lymphadenopathy 9%,
lymphoproliferative disease 11%, pleomorphic adenoma 8%, thyroglossal cyst 5%, carotid body tumour
4%, lipoma and branchial cysts were 3% each, sialolithiasis 2% and one case each of dermoid, sebaceous
cyst, adenoid cystic carcinoma, Kikuchi's disease and Ewing's tumour. Correlation of FNAC with biopsy
was for TB; true positive, 64.5%, true negative 29.03%, false positive 3.22%, false negative 3.22% and for
metastatic lymph node true positive 57.89%, true negative 36.84%, false positive 5.26% and no case of
false negative. The diagnostic yield of FNAC was for TB, accuracy, sensitivity, specificity, positive
predictive value and negative predictive value were 93.54%, 95.23%, 90%, 95.23% and 90% respectively.
Metastatic lymph nodes accuracy sensitivity, specificity, positive predictive value and negative predictive
value were 94.73%, 100%, 87.5%, 91.66% and 100% respectively. Overall diagnostic value of FNAC in
non-thyroidal neck masses with regard to accuracy, sensitivity, specificity, positive predictive value and
negative predictive value were 90%, 90%, 77.42%, 90.41%, 90.41%, and 88.89% respectively.
This descriptive study was conducted at the Department of ENT, Lady Reading Hospital
Peshawar from January to December 2009. Hundred patients with non-thyroidal neck masses fulfilling the
inclusion criteria were included in the study. Fine needle aspirations were performed by the same
