title: Paraneoplastic encephalomyelitis: Is it an oropharyngeal or a lung cancer complication?
abstract: This case report describes a patient with a locally advanced oropharyngeal cancer with a simultaneous paraneoplastic encephalomyelitis. To the best of our knowledge, a paraneoplastic neurological syndrome is a rare complication in head and neck cancer, and has previously not been reported in the literature. One year later, following initial treatment, a small cell lung cancer developed, a tumor frequently associated with this type of paraneoplastic syndrome. The dilemma, therefore, is whether this paraneoplastic symdrome was a secondary complication of the tonsilar concurrent cancer or a metachronous paraneoplastic syndrome prior to small cell lung cancer.
