Pulmonary blastoma: Report of a case

Association between Congenital Lung Malformations and Lung Tumors in Children and Adults: A Systematic Review

“…Whether PPB causes cysts or arises in preexisting cysts is still under debate. Several reports described PPB occurring in association with preexisting [14][15][16][17][18][19][20][21][22][23][24][25] or simultaneosly recognized 26 cystic disease of the lung and taking the form of a unilocular cyst, 16,18,19,[23][24][25] a multilocular cyst, 14,15,18,20,26 or multiple cysts. 21,22 It is not clear whether preexisting cysts have a role in the pathogenesis of the mesenchymal tumors, but it has been suggested that the cysts might serve as a vehicle for the retention and persistence of unstable mesenchymal cells.…”

Pleuropulmonary Blastoma in Congenital Cystic Adenomatoid Malformation: Report of a Case

“…Less frequent symptoms include chest pain, anorexia, weight loss. Occasionally, hemoptisis, abdominal pain and pneumothorax have been reported (2,6,7,12). Distant metastases have been described at presentation, occurring in about 44% of cases in the liver, regional lymphnodes, kidneys, pancreas, adrenal glands, bones and brain (3,9,14).…”

Mesenchymal neoplasia and congenital pulmonary cysts

“…Two others were primitive tumors which, from their description, may have represented embryonal rhabdomyosarcoma [3,6]. A similar case was described by Martinez et al [5]. A similar case was described by Martinez et al [5].…”
