Myokymia (fasciculation) of the tongue as a unique presentation of mucoepidermoid carcinoma.
Neural invasion is a relatively common feature of squamous cell carcinomas of the head and neck and malignant salivary gland tumours. The symptoms depend on the location and the particular nerves involved, and include pain, anaesthesia, paraesthesia and cranial nerve palsy. The present case appears to be unique. A mucoepidermoid carcinoma showed evidence of neural involvement and presented with nerve stimulation inducing myokymia, rather than nerve destruction, which is the usual consequence of tumoral nerve invasion.
