title: Malignant thymoma and myasthenia gravis presenting as polymyositis: a case report.
abstract: Polymyositis revealing myasthenia gravis and malignant thymoma: a case report. The increased frequency of thymoma associated with autoimmune diseases has been well documented in the literature. However the association of polymyositis (PM) and myasthenia gravis (MG) revealing a malignant thymoma is rare. We report a case of a gentleman whose presenting symptoms were those of polymyositis.
