Inflammatory pseudotumors of the lung in children: conservative or aggressive approach?
BACKGROUND
Inflammatory pseudotumors (inflammatory myofibroblastic tumors) of the lung are myofibroblastic lesions of controversial nosology. The concept that these are benign lesions has been recently questioned given their capacity for local invasion and recurrence.


RESULTS
We observed five children with inflammatory pseudotumors of the lung in whom the tumor was resected using the most limited excision possible. Unusually, in all five cases the tumor was localized in the right upper lobe: Three were parenchymal, and the others involved the bronchus. The three parenchymal masses underwent wedge resection, whereas the two bronchial lesions required ex-cision followed by a bronchoplasty and an up-per lobectomy, respectively. In all, the pathology showed a complete resection, and the patients had uneventful recoveries. Follow-ups, including CT and bronchoscopies, ranged from 4 to 8 years (mean of 6.4 years) with no signs of recurrence.


CONCLUSIONS
Our limited experience supports the idea that excisional surgery is the treatment of choice for inflammatory pseudotumors of the lung. Such excisions, both diagnostic and curative, carry minimal risks and avoid unnecessary mutilation. Closely monitored follow-up is mandatory, as the natural history of this lesion is not yet well understood.
