Lesão Tumoral Primária do Pulmão em Adolescente

Primary lung tumors in the pediatric age group are rare, histologically diverse and have different therapeutic approaches. The inflammatory myofibroblastic tumor of the lung accounts for 0.04% - 1.2% of all lung tumors, is more common in children and young adults and its etiology is unknown. The diagnosis is difficult as clinical and radiological findings are highly variable. We report a case of a 15-year-old adolescent who presented with a single pulmonary nodule on a chest radiograph, in the context of a respiratory infection, and whose etiological investigation revealed an inflammatory myofibroblastic tumor of the lung. Atypical resection was performed by video-assisted thoracoscopic surgery, with full recovery. We highlight the rarity of this entity, the need for a high suspicion index and the diagnostic investigation undertaken to reach a definitive diagnosis and a successful outcome.
