Escleromixedema asociado a síntomas neurológicos: tratamiento satisfactorio con inmunoglobulinas

New insights on scleromyxedema

Scleromyxedema is a rare fibromucinous disorders, with several clinical and pathological overlaps with scleroderma and scleredema. Etiopathogenesis remains uncovered, and no explanation has been provided either for the origin of mucin deposition or for the paraprotein role. The disease does not show gender predilection and affects mainly middle-age adults. The course is unpredictable, and prognosis remains guarded for renal, cardiac, and neurologic complications, especially in the setting of dermato-neuro syndrome. A valuable recent progress is the consensus definition of diagnostic criteria and lines of treatment, which hold the promise to improve the early recognition and management of this rare condition worldwide. High-dose intravenous immunoglobulin has been suggested as the first-line treatment either alone or associated with systemic steroids and/or thalidomide. In very recalcitrant cases, adjunctive bortezomib and/or autologous stem cell transplant might be considered. Melphalan treatment was associated with very toxic side effects and actually is no longer recommended.
