Positive CK7 refers to the presence of cytokeratin 7 (CK7) protein in tissue samples, typically analyzed through immunohistochemistry. CK7 is a type of intermediate filament protein expressed in various epithelial tissues, and its positivity can help in the diagnosis and classification of certain tumors. For example, CK7 positivity is often associated with adenocarcinomas of the lung, breast, and ovary, among others, aiding in differentiating between various types of cancers. Its expression pattern can provide important insights into the tumor's origin and behavior.
CK7, or cytokeratin 7, is a protein that is part of the cytoskeletal structure in epithelial cells. Tumors that express CK7 are typically associated with certain types of cancers, such as those originating in the lung, ovary, and breast. The presence of CK7 can help pathologists in diagnosing specific tumors and determining their origin, as different cancers have distinct patterns of cytokeratin expression.
