The cells form large irregular-shaped rosettes with neuropil at the centre (pineocytoma/neurocytoma-type rosette).<br /> <br /> There are no multi-nucleated giant cells, no hyperchromatic nuclei and no mitotic activity.<br /> <br /> The cytoplasm has positive immunostaining with synaptophysin and neuron-specific enolase (NSE). The tumour cells are negative for GFAP and chromogranin A. The Ki-67 stains approximately 5% of cells.<br /> <br /> ===Final diagnosis===<br /> 1-3. PINEAL GLAND:<br /> &lt;BR&gt; - PINEOCYTOMA (WHO GRADE I).</div>
