This tumor has unique clinical associations, most notably with hematological abnormalities and myasthenia gravis. According with the M\u00fcller-Hermelink criteria, there are significant differences between the histological types of thymomas and the association with myasthenia gravis. Among the different histological types, medullary thymoma is the least frequent variant associated with this autoimmune disease. In this report we describe a case of medullary thymoma presenting in a 71-year- old woman with a myasthenic syndrome.<\/jats:p>","DOI":"10.1590\/s0004-282x2000000600020","type":"journal-article","created":{"date-parts":[[2005,4,15]],"date-time":"2005-04-15T14:27:54Z","timestamp":1113575274000},"page":"1110-1114","source":"Crossref","is-referenced-by-count":1,"title":["Invasive medullary thymoma associated with myasthenia gravis: an unusual case"],"prefix":"10.1590","volume":"58","author":[{"given":"JORGE S.","family":"REIS FILHO","sequence":"first","affiliation":[{"name":"Universidade Federal do Paran\u00e1"}]},{"given":"MARIA FERNANDA","family":"MILANEZI","sequence":"additional","affiliation":[{"name":"Universidade do Porto"}]},{"given":"CHRISTIANO G.","family":"MOREIRA","sequence":"additional","affiliation":[{"name":"Universidade Federal do Paran\u00e1"}]},{"given":"LINEU C.","family":"WERNECK","sequence":"additional","affiliation":[{"name":"Universidade Federal do Paran\u00e1"}]},{"given":"PAULO","family":"BOSCARDIN","sequence":"additional","affiliation":[{"name":"Universidade Federal do Paran\u00e1"}]},{"given":"SERGIO OSSAMU","family":"IOSHII","sequence":"additional","affiliation":[{"name":"Universidade Federal do Paran\u00e1;
