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.

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.

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.
