|Test||CK19, IMMUNOHISTOCHEMISTRY STAIN|
|Description||Cytokeratin 19 may be useful in the differential diagnosis of thyroid neoplasms. Papillary thyroid cancers are strongly positive for this marker. CK19 reacts with many benign and malignant epithelial lesions. Malignant breast tumors and other epithelial tumors show positive homogeneous staining. Cervical squamous cell carcinomas, keratinizing and non-keratinizing, as well as adenocarcinomas of the cervix are strongly positive.
