We describe herein the case of a 2-year-old girl found to have a pulmonary
blastoma (PB). The child was admitted to our hospital with the chief compla
ints of coughing and left-sided chest pain. On admission, a chest X-ray rev
ealed a large mass in the left lung, which measured 10 cm in diameter. Comp
uted tomography and magnetic resonance imaging showed a marginally and hete
rogeneously enhanced tumor filling the left hemithorax. Pathologic findings
of the fine-needle aspiration were suggestive of neuroblastoma. Subsequent
ly, a left pneumonectomy with lymph node dissection was performed and histo
pathological examination confirmed that the tumor was a PB (type III). Afte
r the definitive diagnosis was made the patient received combination chemot
herapy, and no evidence of recurrence has been seen in the 5 months since s
urgery.
