[Myasthenia gravis, palindromic rheumatism and systemic lupus erythematosus. A clinical case report].

We describe a case of a 59-year-old white woman, that first developed a myasthenia gravis picture, then palindromic rheumatism and, in the end, systemic lupus erythematosus. We have searched in the literature the common features and the differences between myasthenia gravis and systemic lupus erythematosus. In this report we emphasize the possible connection between palindromic rheumatism and autoimmune diseases.
