Temporal bone rhabdomyosarcomas are rare tumours that occur almost exclusively in children.

They arise most commonly in the middle ear, from which they extend through the mastoid and petrous portions of the temporal bone, eventually invading the cranium.

Age: Usually between 1 to 12 years of age.

Clinical presentation: The child often complains of bloody discharge.

The tumour often presents as a "polyp" in the external auditory meatus and may invade into the middle ear, hence it can be difficult to identify the exact site of origin of the tumour.

Gross:  Lobulated red mass with areas of hemorrhage.

Microscopic features: The rhabdomyosarcomas in this area are mostly embryonal in type.

If untreated the tumour can spread extensively into the cranial cavity, externally, or to the pharyngeal region.
