Organising pneumonia associated with fumaric acid ester treatment for psoriasis.

INTRODUCTION

We present the case of a 49-year old male who presented with dyspnoea, cough, weight loss, night sweats and general malaise. He had been on treatment with oral fumaric acid esters (FAE, Fumaderm®; Biogen Idec GmbH, Ismaning, Germany) for 6 months.

METHODS

Report of a case.

RESULTS

His chest X-ray showed patchy infiltrates in the left upper lobe which failed to resolve under empiric antibiotic therapy. A computed tomography of thorax revealed bilateral, mostly peripheral foci of consolidation with air bronchograms. Transbronchial biopsies showed a pattern of organising pneumonia (OP).

CONCLUSIONS

Therapy with oral prednisolone (40 mg/day) resulted in a rapid clinical and radiological improvement. An association of FAE and OP has not previously been reported.
