What are the best treatments for Carney Complex?

Treatment for Carney Complex (CNC) is primarily focused on the lifelong surveillance and surgical management of the various endocrine and non-endocrine tumors associated with the condition. Because Carney Complex presents with diverse manifestations, there is no single "cure," and care must be highly personalized to address the specific tumors or hormonal imbalances identified in each patient.

How is Carney Complex managed clinically?

Management of Carney Complex centers on early detection through rigorous, lifelong screening protocols. Because patients are at high risk for developing cardiac myxomas, endocrine tumors (such as those affecting the adrenal or pituitary glands), and skin pigmentary changes, treatment is often reactive to the findings of these screenings. For example, cardiac myxomas—a hallmark of Carney Complex—are typically treated with surgical excision to prevent complications like stroke or heart failure.

What are the core components of the treatment plan?

Treatment is multidisciplinary and varies based on the tumor type. Common interventions include:

• Surgical intervention: Often required for cardiac myxomas, thyroid nodules, and primary pigmented nodular adrenocortical disease (PPNAD).


• Endocrine therapy: Managing hormone excess, such as using inhibitors for Cushing’s syndrome or hormone replacement therapy if glands are removed.


• Dermatological monitoring: Regular skin checks for lentigines and blue nevi, which may be removed if they are symptomatic or suspicious.


• Regular imaging: Annual echocardiograms are vital for all patients diagnosed with Carney Complex to screen for heart tumors.

Which specialists should be on the care team?

Due to the multisystem nature of Carney Complex, patients require a coordinated care team. Essential specialists often include:

• Endocrinologists (to manage hormone-secreting tumors)


• Cardiologists (specializing in cardiac myxomas)


• Dermatologists (to monitor skin manifestations)


• Genetic counselors (to assist with family testing and inheritance guidance)

Next steps

• Consult with an endocrinologist or geneticist experienced in rare endocrine neoplasia syndromes.


• Ensure you have a baseline and annual echocardiogram scheduled.
