The exact percentage of glassy cells needed to make the diagnosis of GCC is not well established, but it may range from 30% to 100%[1,9] Ultrastructurally, glassy cells may show intermediate filaments, polyribosomes, tonofibrils, and desmosomes.
Few primitive desmosomes and sparse tonofibrils were rarely observed.
We believe that the positive expression of tumor cells for CK and other epithelial markers and the presence of tonofibrils and desmosomes are proportional to the degree of differentiation of squamous cell component existing in this neoplasm.
