title: Carcinoid tumor of the thymus associated with a parathyroid adenoma.
abstract: A parathyroid adenoma occurred synchronously with a thymic carcinoid tumor in a 34-year-old man. A sibling was known to have an insulinoma, pituitary adenoma, and parathyroid hyperplasia. The simultaneous occurrence of these tumors, in association with the noted family history, suggests a possible multiple endocrine adenomatosis variant. A description of both tumors is provided along with a review of the literature on thymic carcinoid tumors.
