| Introduction |
|---|
Scleromyxedema is a rare connective tissue disorder, characterized by generalized skin induration with waxy yellowred papules. Histological features include cutaneous mucin deposition in the superficial dermis, specifically hyaluronic acid, and fibroblast proliferation. Most patients with this disorder present with monoclonal paraproteinaemia, mainly IgG lambda. Oesophageal abnormalities with dysphagia, muscle weakness, dyspnoea with abnormal diffusing capacity, restrictive lung disease and cor pulmonale, pericardial effusions, central nervous system abnormalities and neuropathies, arthralgias and Raynaud's phenomenon have been observed, and may be associated with significant morbidity and mortality [13]. In post-mortem studies, interstitial and vascular mucin deposition in inner organs has been found inconsistently [2,4]. Renal disease is rare in patients with scleromyxedema. In this article, we report a middle-aged female with scleromyxedema and a scleroderma-like acute renal crisis.
