[Invasive inflammatory pseudotumor of the lung]. / Pseudotumeur inflammatoire pulmonaire invasive.

ABSTRACT

Inflammatory pseudotumor of the lung is an uncommon nonneoplastic tumor of unknown origin. It can mimic lung carcinoma. We report a 65-year-old man who presented with productive cough, weight loss, and a heterogeneous right apical lung condensation. This clinical and radiographic presentation suggested a malignant lung tumor. Surgery was performed and the histological examination of the surgical specimen concluded to an inflammatory pseudotumor. A pneumonectomy was performed because of the tumor extension towards the lower lobe and the mediastinum. No recurrence was observed after a 2-year follow-up. Surgery is essential to confirm the diagnosis of inflammatory pseudotumor. Complete resection is the only guarantee to prevent recurrence.
