NCIt definition : A purely morphologic term that describes a neoplasm in which all or the majority of
the neoplastic cells have a clear cytoplasm, when examined under light microscopy,
using the conventional staining method (H-E). This term does not provide any information
about the nature of the neoplasm (benign or malignant), cell of origin (e.g. epithelial
versus mesenchymal versus hematopoietic), or prognosis. Further examination using
special stains and/or immunohistochemistry is required to appropriately classify this
tumor.;
