Disease Information
Summary
Polyembryoma is a type oftumor that develops from the cells of the gonads (testes in men or ovaries in women). Such tumors are called germ cell tumors. Polyembryomas have a distinctivelook because they are composed of many parts that are shaped like embryos, one of the earliest stages of a developing human during pregnancy. Symptoms of a polyembryoma may include an unusual bump or mass in the abdomen which can cause pain in some individuals; puberty at an unusually young age (known as precocious puberty); or irregularities in a female's menstruation. Treatment begins with surgery and may be followed by chemotherapy and/or radiation therapy. The cause of polyembryoma is not yet known.

When Do Symptoms of Polyembryoma Begin?
Symptoms of this disease may start to appear as a Teenager and as an Adult.
The age symptoms may begin to appear differs between diseases. Symptoms may begin in a single age range, or during several age ranges. The symptoms of some diseases may begin at any age. Knowing when symptoms may have appeared can help medical providers find the correct diagnosis.

Endocrine System
The endocrine system is made up of a series of glands that produce and secrete hormones throughout the body, including the thyroid, pituitary, pineal, and adrenal glands, and the thymus, pancreas, testes, and ovaries. When endocrine glands produce too much or too little hormone, health problems such as weight gain, high blood pressure, and changes in sleep, mood, and behavior can occur. Disease of the endocrine can be diagnosed and treated by an endocrinologist.

Diagnostic Journey
- Find disease-specific information to discuss with your healthcare providers.
- Ask for diagnostic tests.
- Request referrals to specialists.
Knowing where to start your diagnostic journey and how to navigate the next steps are critical to speeding your time to diagnosis
Your Diagnostic Team
How can a diagnostic team help?
Establishing care with a dedicated primary care provider (PCP) is an important early step in your rare disease journey. A PCP can help improve care and shorten the time to diagnosis by providing referrals to the appropriate specialists. These specialists, with advanced training in different body systems or types of diseases, can offer the specialized diagnostic procedures you need.
Use this tool by Medicare to find a PCP in your area by inputting your location and keyword "Primary Care Provider."
A PCP that specializes in the care of children is called a pediatrician. Use this tool by the American Academy of Pediatrics to find a pediatrician in your area by inputting your location.
Diagnostic teams for Polyembryoma may include:
Multidisciplinary Care Centers
Is it time to find a multidisciplinary care center?
If you've visited your PCP, met with specialists, and undergone the recommended tests, but still do not have a confirmed diagnosis, it may be time to visit a multidisciplinary care center. Multidisciplinary care centers are usually teaching, university, or research hospitals that have teams of medical experts and specialists working together in the same location. This means a wide range of diagnostic tests and clinical knowledge are available at one facility, which can help increase communication and collaboration among your care team. The additional resources often available at multidisciplinary centers may help speed the time to diagnosis for rare diseases.

Rare Disease Experts
How can you find a rare disease expert?
If a diagnosis remains unknown despite extensive efforts by your PCP and specialists, it can be challenging to know what kind of expert you may need or where to find one. A rare disease expert is a care provider that has knowledge or training on specific disease(s), but there may only be a few experts in your state, region, or country. Rare disease experts may work at large research or teaching hospitals. In complex cases, coordinating with a network of experts can help your care provider find the right diagnosis.
Contact a GARD Information Specialist for help finding an expert.
You can ask your care providers for help finding an expert or use directory tools to search for experts near you. The National Organization for Rare Disorders (NORD) maintains a list of rare disease centers with experts that work together to find treatments and cures for a broad range of rare diseases. Search NORD's Center Directory to find experts near you.

How Can Patient Organizations Help?
Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.
Services of patient organizations differ, but may include:
- Ways to connect to others and share personal stories
- Easy-to-read information
- Up-to-date treatment and research information
- Patient registries
- Lists of specialists or specialty centers
- Financial aid and travel resources
Please note: GARD provides organizations for informational purposes only and not as an endorsement of their services. Please contact an organization directly if you have questions about the information or resources it provides.
View GARD's criteria for including patient organizations, which can be found under the FAQs on our About page. Request an update or to have your organization added to GARD.

Participate in Research
Clinical studies are part of clinical research and play an important role in medical advances, including for rare diseases. Through clinical studies, researchers may ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.
What Are Clinical Studies?
Clinical studies are medical research involving people as participants. There are two main types of clinical studies:
- Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
- Observational studies involve recording changes over time among a specific group of people in their natural settings.
Why Participate in Clinical Studies?
People participate in clinical trials for many reasons. People with a disease may participate to receive the newest possible treatment and additional care from clinical study staff as well as to help others living with the same or similar disease. Healthy volunteers may participate to help others and to contribute to moving science forward.
To find the right clinical study we recommend you consult your doctors, other trusted medical professionals, and patient organizations. Additionally, you can use ClinicalTrials.gov to search for clinical studies by disease, terms, or location.
What if There Are No Available Clinical Studies?
ResearchMatch helps connect people interested in research studies with researchers from top medical centers across the United States. Anyone from the U.S. can register with this free program funded by NIH. Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate.
Join the All of Us Research Program!
The All of Us Research Program is inviting 1 million people from all backgrounds across the U.S. to help build one of the most diverse health databases in history. Researchers will use the data to learn how our biology, lifestyle, and environment affect health. This may one day help them find ways to treat and prevent diseases.
