Materials and Methods
A systematic review of case reports was conducted by searching PubMed, Scopus, and Google scholar using the following keywords, (1) ’Myasthenia Gravis’ + ’Chronic Myeloid Leukemia,’ (2) ’Myasthenia Gravis’ + ’Polycythemia Vera,’ (3) ’Myasthenia Gravis’ + ’Essential Thrombocythemia,’ (4) ’Myasthenia Gravis’ + ’Primary/ Pre-fibrotic Myelofibrosis’ and (5) ’Myasthenia Gravis’ + ’Myeloproliferative neoplasms/ diseases.’ Articles other than case reports and case series were removed. All case reports of the association of myasthenia gravis with myeloproliferative neoplasms were identified. Cases of MPNs with non-neurological paraneoplastic syndromes were excluded. A Comparative study between the cases was done to identify the chronological order of events and know whether Myasthenia gravis can be considered a possible neurological paraneoplastic syndrome in patients with myeloproliferative neoplasms.
