| ==Overview==
| |
| '''Pleuropulmonary blastoma''' ('''PPB''') is a rare intrathoracic malignancy originating in the [[lung]] or [[pleural cavity]]. Pleuropulmonary blastoma occurs most often in infants and young children.<ref name="pmid11002236">{{cite journal |vauthors=Indolfi P, Casale F, Carli M, etal |title=Pleuropulmonary blastoma: management and prognosis of 11 cases |journal=Cancer |volume=89 |issue=6 |pages=1396–401 |date=September 2000 |pmid=11002236|doi=10.1002/1097-0142(20000915)89:6<1396::AID-CNCR25>3.0.CO;2-2}}</ref>

| | |
| ==Historical Perspective==
| |
| *Pleuropulmonary blastoma was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].
| |
| | |
| ==Classification==
| |
| *Pleuropulmonary blastoma may be classified into 3 groups:
| |
| :* Type I: multicystic lesions
| |
| :* Type II: thickened areas (nodules) within this cystic lesions
| |
| :* Type III: solid masses
| |
| *Type I PPB is made up of mostly [[cysts]], and may be hard to distinguish from benign lung cysts, and there is some evidence that not all type I PPB will progress to types II and III.
| |
|
| |
| ==Pathophysiology==
| |
| *The pathogenesis of pleuropulmonary blastoma is characterized by
| |
| *The p53 mutations/deletions have been associated with the development of pleuropulmonary blastoma.
| |
| *On gross pathology, characteristic findings of pleuropulmonary blastoma, include:
| |
| *On microscopic histopathological analysis, characteristic findings of pleuropulmonary blastoma, include:
| |
|
| |
| ==Causes==
| |
| * Common causes of pleuropulmonary blastoma, include:
| |
| :*Trisomy 8

| :*Trisomy 2
| |
| :*p53 mutations/deletions
| |
| | |
| ==Differentiating [disease name] from other Diseases==
| |
| *Pleuropulmonary blastoma must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as:
| |
| :*[Differential dx1]
| |
| :*[Differential dx2]
| |
| :*[Differential dx3]
| |
|
| |
| ==Epidemiology and Demographics==
| |
| * The prevalence of [disease name] is approximately [number or range] per 100,000 individuals worldwide.
| |
| * In [year], the incidence of [disease name] was estimated to be [number or range] cases per 100,000 individuals in [location].
| |
