08/01/2015 - "All 18 tumors were positive for cytokeratin 7 and CD117. "
12/01/2014 - "However, considering the differential diagnosis, the best discriminator of a secondary tumor is the combination of tumor size, laterality and the pattern of expression of cytokeratin 7 and MUC2."
12/01/2014 - "However, after multivariate analysis, the best predictors of a secondary tumor were a size of 10.0 cm or less, bilaterality and cytokeratin 7 negativity. "

01/01/2015 - "A biopsy of supraclavicular lymph node was performed and the histopathology showed poorly differentiated adenocarcinoma with cytokeratin-7 (CK-7) and thyroid transcription factor-1 (TTF-1) being positive immunohistochemically. "
11/01/2013 - "CCCL tended to be present in older individuals with an adenocarcinoma immunophenotype (cytokeratin 7 and TTF1 positivity). "

03/01/2006 - "The combination of immunohistochemistry for cytokeratin 7 and 20 appeared to be a useful tool in determining the site of origin and helpful for premortem diagnosis of the origin of unknown primary carcinoma."

10/01/2011 - "Additionally, unlike primary carcinomas, the majority (82%) of metastatic NETs were negative for cytokeratin 7, and all were negative for gross cystic disease fluid protein 15 and mammoglobin. "
03/01/2011 - "In four cases, determination of the primary site finally became possible by comparison with the histological findings of operative specimens in past carcinoma and/or in consideration of radiological findings and the results of cytokeratin 7/20 phenotyping. "

01/01/1993 - "Our study demonstrates that this keratin 7 antibody is useful in differentiating between squamous cell carcinoma and adenocarcinoma of the lung and it may be particularly useful in making the correct diagnosis in small lung biopsy specimens."
07/01/2013 - "Cytokeratin 7 (CK7) and Cam 5.2 are often used to differentiate extramammary Paget's disease (EPD) from squamous cell carcinoma (SCC) in situ because they are generally considered to be expressed in the former but not in the latter. "

04/01/2003 - "Cytokeratin 7 and 20 expression in epithelioid sarcoma."
08/01/2009 - "Lung biopsy revealed poorly differentiated adenocarcinoma positive for cytokeratin 7. Renal, sarcoma, and gastrointestinal markers were negative. "
08/01/2010 - "Sarcolectin (SCL) is a 55 kDa protein cross-reacting with a cytokeratin 7 monomer found in placental blood, sarcomas and various tissues. "
07/01/2003 - "Immunohistochemical study of the excised primitive spindle cell sarcoma revealed occasional positive stains by hitherto reported antigens of S-100, cytokeratin 7, high molecular weight cytokeratin (34 beta E12), pankeratin (AE1/AE3), and EMA, which were helpful for the differential diagnosis of other spindle cell sarcomas. "
01/01/2014 - "Expression of markers specific for glandular (TTF-1, napsin A, cytokeratin 7), squamous cell (p40, p63, cytokeratins 5/6, desmocollin-3), and neuroendocrine (chromogranin, synaptophysin, CD56) differentiation was studied in 121 LCC across their entire histological spectrum also using direct sequencing for epidermal growth factor receptor (EGFR) and v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations and FISH analysis for ALK gene translocation.
