Lung Tumors

In children, primary lung tumors are rare, but metastases are much more common. Lung masses in children are ten-times more likely to be a developmental or reactive lesion than a tumor. The ratio of primary tumors to metastatic tumors to non-neoplastic lesions is estimated to be 1:5:60.1 . On the basis of the rarity of primary lung tumors in children, the diagnosis remains a challenge. Several cases are asymptomatic or present with non-specific symptoms, and they are discovered incidentally.
