Recurrence of Inflammatory Pseudotumor of the Lung after Eleven Years of Remission

Abstract

The standard treatment of inflammatory pseudotumor of the lung is surgical excision. However, little data is available on steroid therapy in patients with the unresectable disease. Here, we report a patient with recurrent inflammatory pseudotumor of the lung with pleural involvement who had been successfully treated with corticosteroid eleven years previously. Like the previous treatment, retreatment with corticosteroid proved to be effective for the recurred lesion. In addition, the patient had developed extramammary Paget's disease and bladder cancer after the initial onset of inflammatory pseudotumor. Steroid therapy could be an optional modality in treating unresectable inflammatory pseudotumor, although long-term follow-up is definitely necessary.
