Poems syndrome (polyneuropathy, organomegaly, endocrine abnormality, M-protein, plasma cell dyscrasia, and skin lesions) is a plasma cell dyscrasia whose pathogenesis is unknown. We report a 60 years old woman that presented a tetraparesis caused by a sensitive motor polyneuropathy. The subsequent work up revealed an IgA type monoclonal gammopathy, hepatomegaly, hyperestrogenism, primary adrenal failure, hypothyroidism, hyperpigmentation and erythematous lesions in the skin and ankle edema. The patient is being treated with prednisone 0.5 mg/kg and levothyroxine 100 microg/day, with partial remission of her symptoms.
