| anonymous | Olfactory neuroblastoma (100%) | The tumour cells may be positive for NSE, chromogranin, neurofilament. The cells at the periphery may be positive for S100. | 100 |

| anonymous | Olfactory neuroblastoma | Confirm diagnosis by immunostaining for synaptophysin and chromogranin. | 100 |
| anonymous | ALVEOLAR RHABDOMYOSARCOMA 70%, OLFACTORY NEUROBLASTOMA 30%. | In the H & E section, there is a significant histologic overlap between the 2 differential. Immunostains are important for diagnosis. Muscle markers eg. desmin, actin for rhabdomyosarcoma; neuroendocrine markers eg. synaptophysin for olfactory neuroblastoma. | 60 |
| anonymous | Small round cell tumor, consistent with olfactory neuroblastoma.(100%) | Confirm by immunostains. The cells should be positive for neuroendocrine markers such as neuron specific enolase, chromogranin and synaptophysin. | 100 |
| anonymous | Nasal mass - malignant small round cell tumour, favour alveolar rhabdomyosarcoma 80% | Other differential diagnoses of small round cell tumours should be considered too, and can be ruled in/out by immunohistochemistry. Electron microscopy is performed as a last resort. | 50 |
