MEN1 and prolactin-producing pituitary gland adenoma: One man showed a well-differentiated lung carcinoid at the age of 49 years as the first manifestation of MEN1 (0.69% of MEN1 affected patients); he was clinically and genetically diagnosed with MEN1 at the age of 50 after showing a well-differenced gastric NF-NET and a micro-PRLoma (interestingly at the age of 59 he had not manifested PHPT yet).
