The sections show a sheeting tumour with abundant and eosinophilic cytoplasm. The tumour cell cell membranes are prominent and plant-like. Perinuclear clearing is present. Binucleation is frequent and the nuclear membranes moderately irregular. No definite papillae or macrophages are present. Nucleoli are not prominent. Small blood vessels are not prominent. | |||

The sections show a tumour composed of compact nests. The cytoplasm is abundant and eosinophilic. Perinuclear clearing is prominent. Binucleation is frequent and the nuclear membranes moderately irregular to round. No definite papillae or macrophages are present. Nucleoli are not prominent. | The sections show a tumour composed of compact nests. The cytoplasm is abundant and eosinophilic. Perinuclear clearing is prominent.
