Carney triad

The Carney triad (not to be confused with the Carney complex) is a rare syndrome defined by the coexistence of three tumours:

• extra-adrenal paraganglioma (e.g. extra-adrenal phaeochromocytoma): initially, only functioning extra-adrenal paragangliomas were included, but subsequent work includes non-functioning extra-adrenal paragangliomas ¹
• gastric gastrointestinal stromal tumors (GIST)
• pulmonary chondroma

In most cases, only 2 of the 3 tumours are present at the time of diagnosis. It typically affects young people.
