Abstract

  Oral squamous cell cancers usually metastasize by lymphatic route, to the neck lymph nodes and in few cases by hematogenous route to other organs. The perineural invasion is a less prevalent phenomenon. It occurs when the growth penetrates nerve sheath of nerve present in vicinity and grows alongside nerve bundle. It is associated with poor prognosis and high mortality as it is often missed preoperatively resulting in incomplete removal of the disease. Here we present a case of buccal carcinoma where the perineural spread along mandibular nerve led to malignancy spread to the skull base, causing inflammation of cavernous sinus and leading to lateral rectus palsy due to abducens nerve involvement.
