[Myasthenic syndrome disclosing Hodgkin disease].

A case of myasthenia associated with Hodgkin's disease with probable invasion of the thymus is reported. Five cases of association between lymphomatous thymoma and myasthenia (2 Hodgkin's thymomas and 3 non-Hodgkin's lymphomatous thymomas) have previously been reported. Myasthenia healed after the lymphoma was treated. This association raises pathogenic problems in the 3 cases of non-Hodgkin's thymoma where invasion of the thymus erased all its normal structure.
