Pathologic evaluation revealed dilated vascular spaces with normal endothelial cells surrounded by a proliferation of cells with eosinophilic cytoplasm and small, round nuclei, consistent with a ...

3b). The neoplastic cells had distinct cell borders and moderate amounts of eosinophilic cytoplasm. Nuclei were round to reniform and had a moderate degree of anisokaryosis. Binucleated cells were ...

The cells have tendency for clustering rather than even distribution Large mononuclear cells, their nucleoli tend to be basophilic rather than eosinophilic and their cytoplasm is basophilic ...
