title: [Thymoma and lupus: apropos of a case with recurrences and histological dedifferentiation].
abstract: A case of thymoma associated with chronic lupus erythematosus is reported. The course of the lupus was parallel to that of the thymoma, with several successive relapses. Histologically, the thymoma became increasingly undifferentiated. Chemotherapy only resulted in a few months of remission.
