Children with pleuropulmonary blastoma (PPB) may experience the following symptoms or signs. Symptoms are changes that you can feel in your body. Signs are changes in something measured, like by taking your blood pressure or doing a lab test. Together, symptoms and signs can help describe a medical problem. Sometimes, children with PPB do not have any of the symptoms and signs described below. Or, the cause of a symptom or sign may be a medical condition that is a not tumor. Because PPB is so rare, doctors often believe at first examination that the symptoms are caused by a common childhood illness.

There are 2 common sets of symptoms that may indicate PPB:

  • Sudden, stressful breathing may be caused by air escaping from the lung cysts into the chest cavity. This is called pneumothorax, meaning there is air in the chest cavity. It is important to note that there are many other causes of pneumothorax.

  • Symptoms of PPB may be exactly the same as symptoms of pneumonia, which is a lung/respiratory infection. These symptoms may include feeling generally unwell, a cough, a fever, and pain in the chest. Even when a chest x-ray is done, it may be first interpreted as pneumonia. It is common for children with PPB to have been treated for 2 to 3 weeks for pneumonia before more tests show that they likely have a tumor in the chest.

In addition, sometimes a lung cyst or tumor may be found when a chest x-ray is taken for another reason. See the Diagnosis section for more information on chest x-rays.

If you are concerned about any changes your child experiences, please talk with your child’s doctor. Your child's doctor will ask how long and how often your child has been experiencing the symptom(s), in addition to other questions. This is to help figure out the cause of the problem, called a diagnosis.

If PPB is diagnosed, relieving symptoms remains an important part of your child’s medical care and treatment. Managing symptoms may also be called "palliative care" or "supportive care." It is often started soon after diagnosis and continued throughout treatment. Be sure to talk with your child's health care team about the symptoms your child experiences, including any new symptoms or a change in symptoms.
