[The association of myasthenia and disseminated lupus erythematosus. 2 cases].

Two cases of the association myasthenia/systemic lupus erythematosus are described. This association is rare but of particular interest from a pathogenic point of view. The discussion includes the suggestion of an immunological disturbance which might be the common denominator of the two disorders. Recent data concerning the role of the thymus and of "suppressor" T cells support such a hypothesis.
