Myasthenia gravis and premature ovarian failure



We describe a patient who developed seropositive myasthenia gravis 16 years after she was diagnosed with autoimmune premature ovarian failure with antibodies to the receptor for follicle-stimulating hormone (FSH). Although thymectomy led to improvement of her myasthenic symptoms, menses did not resume. Such combined seropositivity for antibodies to acetylcholine and ovarian hormone receptors in a patient with myasthenia gravis and premature ovarian failure may reflect common disease mechanisms, although the precise pathogenesis of these disorders remains ill-defined.
