Glial fibrillary acid protein immunoreactivity in fine-needle aspiration of salivary gland lesions: a useful adjunct for the differential diagnosis of salivary gland neoplasms.


The value of immunocytochemical staining for glial fibrillary acid protein (GFAP) in salivary gland lesions was investigated in 33 fine-needle aspiration smears. The study utilized cytologic material from ten pleomorphic adenomas, six normal salivary glands, three cases of chronic sialadenitis, three Warthin's tumors, two adenoid cystic carcinomas, three… (More)
