Immunohistochemical staining was performed using rabbit monoclonal cytokeratin
The tumor cells were also focally positive for desmin, smooth muscle actin (SMA), and cytokeratin
Among the cytokeratin
markers used in our study, CK17 proved to be the most reliable and useful in differentiating the three types of cystic jaw lesion.
But they express diffuse positivity for cytokeratins
which, if positive, was only focal as per our findings.
A positive cytokeratin
immunostain in the invasive tumour cells, if performed alone, will further contribute to misinterpretation of an epithelioid angiosarcoma as a carcinoma.
Based on our analysis, 71 % of the "triple negative" cases showed expression of at least one basal cytokeratin
According to morphological, anatomical, and histopathological findings and to positive immunoreactivity for cytokeratin
, the tumor was characterized as acinar adenocarcinoma in the lung and in the nodes identified in the abdominal cavity.
Immunohistochemical stains on cell block sections in both cases were positive for CK7 (Figures 4a and 4b), EMA and cytokeratin

Immunohistochemical examination revealed positive reaction for cytokeratin

These new small proteins in the study were derived from cytokeratin
6A, one of the filament proteins that connect to form a mesh throughout the cytoplasm of epithelial cells.
15 December 2011 - Biocept Inc, a US-based laboratory specialised in the detection of circulating tumour cells (CTCs) in cancer patients, said on Wednesday that the company's new platform for the detection of Cytokeratin
Positive (CK+) and Cytokeratin
Negative (CK-) CTCs has been described in a publication in the latest issue of the Cancer Discovery journal.
Suprapubic region, Paget's cells, cytokeratin
7, carcinoembryonic antigen.
The cells stained positive for Chromogranin, Synaptophysin and Cytokeratin
