Scleromyxoedema is a rare mucinosis that primarily affects the skin. It is associated with monoclonal gammopathy and has many extracutaneous manifestations, however, renal involvement is rare. We report the case of a woman with monoclonal gammopathy and scleromyxoedema presenting with progressive exertional dyspnoea and acute renal failure. Workup of her renal failure revealed monoclonal gammopathy associated C3 glomerulonephritis. She was treated with intravenous steroids and discharged with plans to pursue annual monoclonal gammopathy laboratory monitoring. Given the rarity of renal scleromyxoedema, careful investigation of extracutaneous manifestations and comorbidities is critical to discern the primary pathological process in patients with scleromyxoedema who develop renal insufficiency.
