Adrenocortical carcinoma (ACC) is a cancer of the adrenal glands. The adrenal glands are two triangle-shaped glands. One gland is located on top of each kidney.

Causes

ACC is most common in children younger than 5 years old and adults in their 40s and 50s.

The condition may be linked to a cancer syndrome that is passed down through families (inherited). Both men and women can develop this tumor.

ACC can produce the hormones cortisol, aldosterone, estrogen, or testosterone, as well as other hormones. In women the tumor often releases these hormones, which can lead to male characteristics.

ACC is very rare. The cause is unknown.

Symptoms

Symptoms of increased cortisol or other adrenal gland hormones may include:

Symptoms of increased aldosterone are the same as symptoms of low potassium, and include:

  • Muscle cramps
  • Weakness
  • Pain in the abdomen 

Exams and Tests

 The health care provider will perform a physical exam and ask about your symptoms.

Blood tests will be done to check hormone levels:

  • ACTH level will be low.
  • Aldosterone level will be high.
  • Cortisol level will be high.
  • Potassium level will be low.
  • Male or female hormones may be abnormally high.

Imaging tests of the abdomen may include:

  • Ultrasound
  • CT scan
  • MRI
  • PET scan

Treatment

Primary treatment is surgery to remove the tumor. ACC may not improve with chemotherapy. Medicines may be given to reduce production of cortisol, which causes many of the symptoms.

Outlook (Prognosis)

The outcome depends on how early the diagnosis is made and whether the tumor has spread (metastasized). Tumors that have spread usually lead to death within 1 to 3 years.

Possible Complications

The tumor can spread to the liver, bone, lung, or other areas.

When to Contact a Medical Professional

Call your provider if you or your child has symptoms of ACC, Cushing syndrome, or failure to grow.
