General description

Anti-CK 5 & 6 positivity is seen in 65% to 100% of epithelioid mesotheliomas, in 0% to 19% of lung adenocarcinomas, and in 22% to 80% of serous carcinoma of the ovary and peritoneum. Keratin 5 & 6 expression in lung adenocarcinoma is not common, and when it occurs, the reaction is usually confined to small focal areas or scattered cells. The most probable cause of this finding is the presence of squamous differentiation of lung adenocarcinoma. Anti-CK 5 & 6 positivity has been useful in recognizing squamous cell carcinoma of the skin. Less than 10% of carcinomas of the breast, colon, and prostate stain positively for this marker. Anti-CK 5 & 6 has also been used successfully as a myoepithelial cell marker in the prostate and breast to determine malignancy. Anti-CK 5 & 6 is a useful marker to distinguish lung squamous cell carcinoma from lung adenocarcinoma and large cell carcinoma within a panel including antibodies against TTF-1, Napsin A, p63, SOX-2, desmocollin3, and desmoglein3.

We evaluated the sensitivity and specificity of cytokeratin (CK) 5/6 for distinguishing foci of atrophy from prostatic adenocarcinoma with and without previous hormonal adjuvant therapy and observed the intensity and pattern of staining in mimickers of prostatic adenocarcinoma (basal cell

Previous studies have shown that basal-type cytokeratins (CKs) can distinguish usual ductal hyperplasia (UDH) from the spectrum of atypical ductal hyperplasia (ADH), ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). Indeed, expression of these CKs is weak

Cutaneous spindle cell squamous cell carcinoma (SSCC) is a challenging diagnosis since it may be difficult to distinguish from spindle cell melanoma, leiomyosarcoma and atypical fibroxanthoma. Furthermore, it may be difficult to demonstrate epithelial differentiation by a traditional immunohistochemical panel.
