Steroid Responsive Parenchymal Lung Involvement and Acute Renal Failure in a Patient with Relapsing Polychondritis

Relapsing polychondritis is a multisystem disorder affecting cartilaginous structures like ear, nose, laryngotracheal tree and proteogylcan rich structures like eyes. Kidney involvement has also been reported in the absence of associated conditions like SLE and vasculitides but parenchymal lung involvement has not been reported in the English literature. One such case of relapsing polychondritis who had parenchymal lung involvement with respiratory failure, renal failue and pancytopenia is described. All these complications recovered with institution of corticosteroids.
