What is Carney complex?
Carney complex is a disorder characterized by an increased risk of several types of tumors. Affected individuals also usually have changes in skin coloring (pigmentation). Signs and symptoms of this condition commonly begin in the teens or early adulthood. Individuals with Carney complex are at increased risk of developing noncancerous (benign) tumors called myxomas in the heart (cardiac myxoma) and other parts of the body. Cardiac myxomas may be found in any of the four chambers of the heart and can develop in more than one chamber. These tumors can block the flow of blood through the heart, causing serious complications or sudden death. Myxomas may also develop on the skin and in internal organs. Skin myxomas appear as small bumps on the surface of the skin or as lumps underneath the skin. In Carney complex, myxomas have a tendency to recur after they are removed. Individuals with Carney complex also develop tumors in hormone-producing (endocrine) glands, such as the adrenal glands l
