Notably, with respect to the overall MEN1 presentation, we mention adults with two lipomas [77] or a single giant cervical lipoma [125]; for the synchronous thyroid malignancy of papillary [81] and medullary type in a RET-negative patient [128], two MEN1 subjects displayed a thymus carcinoid as the first MEN1 manifestation [129,132]. The gene discussed is MEN1; the disease is lipoma.
