Adrenal Cortical Carcinoma (ACC) is a rare, aggressive malignancy that originates in the outer layer of the adrenal gland, known as the adrenal cortex. It can disrupt the body's delicate hormonal balance by overproducing steroid hormones, leading to significant systemic health challenges. What exactly is Adrenal Cortical Carcinoma (ACC)? Adrenal Cortical Carcinoma (ACC) is a rare cancer that develops in the cortex of one or both adrenal glands, which are small, triangle-shaped glands located on top of the kidneys.

Adrenal Cortical Carcinoma (ACC) is a rare, aggressive malignancy that originates in the outer layer of the adrenal gland, known as the adrenal cortex. It can disrupt the body's delicate hormonal balance by overproducing steroid hormones, leading to significant systemic health challenges.
What exactly is Adrenal Cortical Carcinoma (ACC)?
Adrenal Cortical Carcinoma (ACC) is a rare cancer that develops in the cortex of one or both adrenal glands, which are small, triangle-shaped glands located on top of the kidneys. Because the adrenal cortex produces vital hormones—such as cortisol, aldosterone, and sex hormones—an Adrenal Cortical Carcinoma (ACC) tumor can cause "hormone excess" syndromes that fundamentally alter metabolism, blood pressure, and secondary sexual characteristics.
How common is Adrenal Cortical Carcinoma (ACC)?
Adrenal Cortical Carcinoma (ACC) is classified as an orphan disease due to its rarity, with an estimated annual incidence of approximately 0.7 to 2 cases per million people worldwide. In our DiseaseMaps.org community, 265 people with Adrenal Cortical Carcinoma (ACC) have joined to share their unique experiences and support one another.
Who is typically affected by this condition?
While Adrenal Cortical Carcinoma (ACC) can occur at any age, it typically follows a bimodal distribution, with peaks in early childhood (before age 5) and in adulthood (between ages 40 and 50). Women are slightly more likely to be diagnosed with Adrenal Cortical Carcinoma (ACC) than men. Key characteristics include:
- Hormonal Symptoms: Often presents with Cushing’s syndrome (weight gain, high blood pressure) or virilization (excessive body hair, acne).
- Genetic Associations: A subset of cases is linked to hereditary syndromes, such as Li-Fraumeni syndrome or Beckwith-Wiedemann syndrome.
- Tumor Behavior: Unlike benign adrenal adenomas, Adrenal Cortical Carcinoma (ACC) is characterized by rapid growth and a high potential to spread to the liver, lungs, or lymph nodes.
Next steps
- Consult an endocrinologist or an oncology specialist who focuses on adrenal malignancies.
- Request a referral to a high-volume center of excellence for specialized surgical and medical management.
- Connect with the 265 members of the DiseaseMaps.org community to share resources and experiences.
- Inquire about clinical trials for targeted therapies if standard treatments are insufficient.
