Abstract:
We report the results of morphological study of cervical lymph node metastasis of unknown primary tumor at K Hospital from January 1999 to December 2000. Cytological diagnosis had true positive rate in 69.4% false positive rate in 16.6% and false negative rate in 13.8%. The most common histological types are undifferentiated carcinoma (36.3%) and nonkeratinizing squamous cell carcinoma (30%). Immunohistological study is very helpful in the confirmation of epithelial nature of undifferentiated carcinoma
