Embryonal rhabdomyosarcoma arising in the masseter muscle as a second malignant neoplasm.

A case is reported about a patient who was originally treated for bilateral retinoblastoma and subsequently developed an embryonal rhabdomyosarcoma in the masseter. Such patients have a genetic predisposition to a second malignancy that statistically far exceeds the rate for the general population. In addition, current treatment methods also increase the patient's susceptibility to another malignancy. This case emphasizes the necessity of maintaining a high degree of clinical suspicion in the evaluation of any lesion that may appear subsequent to the treatment of cancer in children, particularly bilateral retinoblastoma.

Motor-evoked potentials in masseter muscle by electrical and magnetic stimulation in intact alert man.

The electromyographic responses of the masseter after different types of transcranial stimulation were recorded with surface and needle electrodes. Magnetic stimulation at 4 cm lateral to the vertex on the biauricular line elicited MEPs in the contralateral masseter (latency 6.9 ms) due to activation of motor cortex or adjacent elements along the cortico-nuclear pathway. The ipsilateral responses to the same stimuli and to more lateral ones had shorter latencies and were ascribed to direct stimulation of the trigeminal nerve, probably its intracisternal portion. This was also the probable origin of the ipsilateral MEPs after both anodic and cathodic bipolar electrical stimulation at 7 and 11 cm lateral to the vertex on the biauricular line.
