[Association between mycosis fungoides and myasthenia gravis (author's transl)]

Myasthenia gravis characterized by physical examination, electrophysiologic abnormalities, ephedronium test, without thymoma, associated in a 47 year-old-man, with mycosis fungoides. Myasthenia gravis began two years after the onset of mycosis fungoides, and the patient died of infection four years after the development of the cutaneous lymphoma. At autopsy, there was no visceral involvement. Myasthenia gravis and lymphoma rarely coexist; the occurrence of myasthenia gravis shortly after the onset of mycosis fungoides suggests that the two disorders may be linked by immunological abnormalities.
