Abstract
A 41-yr-old woman manifested a polyneuropathy, anasarca, pseudotumor cerebri, hyperhidrosis and hyperpigmentation of the skin, generalized lymphadenopathy, distal esophageal dysphagia, pleuritis, platelike pulmonary atelectasis, fluctuating renal insufficiency, hepatosplenomegaly, amenorrhea, and slight fever suggesting a connective-tissue disorder. Extensive clinical and laboratory evaluation did not support the initial impression progressive systemic sclerosis or systemic lupus erythematosus but did show nonnecrotizing vascular changes, mild polyclonal gammopathy, and low thyroxine levels similar to the syndrome of polyneuropathy and endocrine disturbances recently reported from Japan. The impressive response to moderate-dose corticosteroids and exacerbation on withdrawal require diagnostic awareness of this insidiously progressive multisystem disorder. A bland vasculopathic process resulting from metabolic or immunologic disturbances appears to be the best explanation for this new syndrome, which was previously recognized only in Japan.
