Unexpected vocal cord paralysis and myasthenia gravis in a patient with squamous cell lung cancer

we report a 55-year-old-male with advanced squamous cell lung carcinoma, presenting a unilateral vocal cord paralysis immediately after the treatment with gemcitabine, and myasthenia gravis one week after. to date, there aren't any data in the literature describing casual relationship between non small cell lung cancer and myasthenia gravis; here we suggest that myasthenia gravis simultaneous to lung cancer might be a rare form of paraneoplastic syndrome. it is impossible to find a single cause for our patient vocal cord paralysis: it could, in fact, have a multifactorial pathogenesis, not excluding the possibility of a single rare paraneoplastic syndrome, which includes both myasthenia gravis and vocal cord paralysis
