| The less mature neurons had abundant pink cytoplasm with central to slightly eccentric nuclei and conspicuous nucleoli. |
| The cells were characterized by large vesicular nuclei with single large nucleoli. |
| Electron microscopy revealed polygonal tumor cells with round nuclei having slightly irregular contours and prominent nucleoli. |
| The cells possessed eosinophilic cytoplasm, well-defined cell borders, and vesicular nuclei with small, conspicuous nucleoli. |
| The bone marrow was replaced by an infiltrate of blast cells with medium-sized nuclei, multiple nucleoli, and moderate amounts of cytoplasm. |
| The tumor cells had slightly eosinophilic cytoplasm and pleomorphic nuclei with prominent nucleoli. |
