This study was undertaken to assess the utility of combined cytokeratin (CK) 7/20 immunoprofile determination in malignant cytologic cell blocks as an aid to the identification of tumor primary site of origin. Fifty-one cases in which CK 7/20 immunocytochemistry was performed as part of the initial
