[Inflammatory pseudotumor of the lung. Case report].

Inflammatory pseudotumor of the lung is a rare entity, of unknown etiology and variable clinical evolution. The histological variety of this entity makes the diagnosis difficult, which is generally obtained after surgical removal of the lesion. The authors report the clinical case of a 32 years old woman presenting with hemoptysis and radiologic appearance of aspergilloma. The lesion was surgically removed and the diagnosis of inflammatory pseudotumor of the lung was confirmed by pathologic and immunohistochemical analysis.
