Types
Pleuropulmonary blastoma is classified into 3 types:
- Type I is multicystic
- Type II shows thickening areas (nodules) within this cystic lesion
- Type III shows 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. Types II and III are aggressive, and cerebral metastasis is more frequent in PPB than in other childhood sarcomas.

Famous quotes containing the word types:
“He types his laboured column—weary drudge!
Senile fudge and solemn:
Spare, editor, to condemn
These dry leaves of his autumn.”
—Robertson Davies (b. 1913)
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“The rank and file have let their servants become their masters and dictators.... Provision should be made in all union constitutions for the recall of leaders. Big salaries should not be paid. Career hunters should be driven out, as well as leaders who use labor for political ends. These types are menaces to the advancement of labor.”
—Mother Jones (1830–1930)
