Introduction: The association between pituitary adenoma and hyperparathyroidism is the main feature of multiple endocrine neoplasia (MEN) 1 but also for a novel MEN4 syndrome. Germline mutations in the cyclin-dependent kinase (CDK) inhibitor 1b gene (CDKN1B) were identified in patients with MEN4. The most common phenotype of the 19 established cases of MEN4 that have been described since now is primary hyperparathyroidism (PHPT) followed by pituitary adenomas. There are a limi...
