title: Malignant thymic carcinoid in multiple endocrine neoplasia type I syndrome: case report and literature review.
abstract: OBJECTIVE
  To describe a case of thymic carcinoid tumor in association with multiple endocrine neoplasia type I (MEN I) and discuss the various manifestations of this syndrome.
  
  
  METHODS
  We present the clinical and laboratory data, including histopathologic and immunocytochemical findings, for our current patient and also review the literature on MEN I syndromes.
  
  
  RESULTS
  In a 46-year-old Caucasian man with no family history of multiple endocrine neoplasia, numerous MEN I lesions developed over time. The patient had gastrinoma of the duodenum, Zollinger-Ellison syndrome, hyperparathyroidism, a nonfunctioning adrenal mass, and foregut carcinoid tumors, including gastric and malignant thymic carcinoids. He sequentially underwent partial gastrectomy in conjunction with Billroth II anastomosis, a four-gland parathyroidectomy, and palliative radiotherapy for malignant carcinoid tumor, as well as endoscopic excision of accessible tumors.
  
  
  CONCLUSIONS
  The involvement in MEN I can be clinically complex. Early detection of MEN I lesions will facilitate timely implementation of treatment and help minimize complications.
