A 23yr old girl with abdominal pain has an endoscopy which reveals a smooth round mass projecting from the wall of her stomach. Histology confirms this is a Gastrointestinal Stromal Tumour (GIST). Subsequent chest x-ray reveals a pulmonary nodule containing ‘popcorn calcification’ in its centre. Which other tumour is this girl at risk of?

Correct Answer: 
Phaeochromocytoma

Carcinoid

FNH

Phaeochromocytoma

Pituitary Adenoma

Medullary Thyroid Tumour

Carney’s triad is one of the Multiple Endocrine Neoplasia syndromes, and it is characterised by 3 tumours: GIST, Pulmonary Hamartomas (chondromas), and extra-adrenal phaeochromocytomas (also referred to as extra-adrenal paragangliogliomas). The calcification described within the lung nodule is characteristic of a pulmonary hamartoma.
