Inflammatory pseudotumors of the lung.

Two unusual cases of inflammatory pseudotumors in young female patients are described. One presented with massive hemoptysis and a solitary circumscribed mass treated with urgent lobectomy. The second presented initially with cough and a small right lower lobe mass. She presented again, 8 years later, with a lung mass so expanded as to necessitate a pneumonectomy with partial resection of surrounding structures. Both cases indicate the need for early and complete removal of the inflammatory pseudotumors.
