Pleuropulmonary blastoma

Common Name(s)

Pleuropulmonary blastoma

Pleuropulmonary blastoma (PPB) is a rare pediatric tumor of the lung that arises during fetal lung development and is often part of an inherited cancer syndrome ({5:Hill et al., 2009}). PPBs contain both epithelial and mesenchymal cells. Early in tumorigenesis, cysts form in lung airspaces, and these cysts are lined with benign-appearing epithelium. Mesenchymal cells susceptible to malignant transformation reside within the cyst walls and form a dense 'cambium' layer beneath the epithelial lining. In a subset of patients, overgrowth of the mesenchymal cells produces a sarcoma, a transition that is associated with a poorer prognosis ({6:Priest et al., 1996}). In approximately 35% of families in which a child has PPB, the patient or a family member manifests 1 or more additional conditions from an unusual array of dysontogenetic-dysplastic and malignant conditions, known as the 'PPB family tumor and dysplasia syndrome' (PPBFTDS). Cystic nephroma, which are benign lesions of the kidney, are found in 9 to 10% of family members affected by PPB (summary by {1:Bahubeshi et al., 2010}). Larger studies have shown that DICER1 mutations are associated with a variety of tumor types, indicating that this disorder can be considered a tumor predisposition syndrome (summary by {7:Slade et al., 2011}).

Infant pleuropulmonary blastoma: report of a rare case and review of literature.
 

Author(s): Hong Zhang, Chun-Wei Xu, Jian-Guo Wei, Guang-Jun Zhu, Sheng Xu, Jin Wang

Journal:

 

In infants, pleuropulmonary blastoma is a rare but aggressive tumor. The typical histopathological presentation includes the aggregation of malignant primitive small cells, usually observed in sheets. So as to provide proper and timely treatment, the differential diagnosis includes ...

Can congenital pulmonary airway malformation be distinguished from Type I pleuropulmonary blastoma based on clinical and radiological features?
 

Author(s): Adina Feinberg, Nigel J Hall, Gretchen M Williams, Kris Ann P Schultz, Doug Miniati, D Ashley Hill, Louis P Dehner, Yoav H Messinger, Jacob C Langer

Journal: J. Pediatr. Surg.. 2016 Jan;51(1):33-7.

 

The management of congenital cystic lung lesions is controversial. Arguments for routine resection during infancy include the possibility of the lesion being Type I pleuropulmonary blastoma (PPB) rather than a cystic congenital pulmonary airway malformation (CPAM). We aimed to identify ...

Insulin-like Growth Factor 2 Gene Expression Molecularly Differentiates Pleuropulmonary Blastoma and Embryonal Rhabdomyosarcoma.
 

Author(s): Rajkumar Venkatramani, Timothy J Triche, Larry Wang, Hiroyuki Shimada, Leo Mascarenhas

Journal: J. Pediatr. Hematol. Oncol.. 2015 Aug;37(6):e356-60.

 

The sarcomatous element in pleuropulmonary blastoma (PPB) is often histologically indistinguishable from embryonal rhabdomyosarcoma (ERMS). A diagnosis of PPB is often made after definitive surgical resection based on pathologic features, most notably the presence of hamartomatous ...

Pleuropulmonary blastoma. The so-called pulmonary blastoma of childhood.
 

Author(s): J C Manivel, J R Priest, J Watterson, M Steiner, W G Woods, M R Wick, L P Dehner

Journal: Cancer. 1988 Oct;62(8):1516-26.

 

The authors studied 11 pediatric intrathoracic neoplasms that share clinicopathologic features and constitute a specific tumor in children. These neoplasms were intrapulmonary, mediastinal, or pleural-based masses. A common histologic feature was the presence of small, primitive cells ...
