Infrequently, neuroendocrine neoplasms (NENs) connected to MEN1 are diagnosed in diverse anatomical sites, including the stomach, thymus, lung, bronchopulmonary tract (in 3–10% of cases), and, more recently, in the female breast (about 7%) [1,2,5]. This evidence concerns the gene MEN1 and neuroendocrine neoplasm.
