This disease is grouped under:

ACTH-secreting pituitary adenoma is a condition characterized by elevated levels of a hormone called cortisol secreted by a tumor in the pituitary gland. It is part of a group of diseases that cause Cushing’s syndrome, characterized by signs and symptoms that may include weight gain around the trunk and in the face, stretch marks, easy bruising, a hump on the upper back, muscle weakness, tiredness, thin bones that are prone to fracture (osteoporosis), mood disorders and memory problems, as well as an increased risk of infections, high blood pressure and diabetes. Women may have irregular menses and a lot of hair in the body (hirsutism). It  occurs when a benign pituitary tumor (adenoma) or pituitary hyperplasia causes the adrenal glands to produce large amounts of cortisol.  Some cases are caused by somatic mutations in the AIP and the GNAS genes. Rarely, an ACTH-secreting pituitary adenoma can be inherited, either as an isolated condition or as part of a genetic syndrome (such as multiple endocrine neoplasia type 1 (MEN1) and familial isolated pituitary adenoma), but most cases are sporadic.[1] Treatment generally involves surgery to remove the tumor and medications to decrease cortisol levels.[2]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.
