  • Title: The association of neurofibromatosis, pheochromocytoma, and somatostatin-rich duodenal carcinoid tumor.
    Author: Wheeler MH, Curley IR, Williams ED.
    Journal: Surgery; 1986 Dec; 100(6):1163-9. PubMed ID: 2878497.
    Abstract:
    The association of neurofibromatosis and pheochromocytoma is well recognized; more recently, attention has been drawn to links between neurofibromatosis, pheochromocytoma, and ampullary somatostatin-rich carcinoid. Because of this association, the duodenum was explored during a recent laparotomy for resection of bilateral pheochromocytoma in a patient with von Recklinghausen's disease. A clinically unsuspected ampullary tumor was discovered; this proved to be in part a ganglioneuroma and in part a somatostatin-rich carcinoid. This paper presents full details of this carefully investigated and documented case and reviews the recent advances in this field. These studies lead us to conclude that: the clinical association of neurofibromatosis, pheochromocytoma, and D cell carcinoids ("somatostatinomas") of the ampullary region is confirmed; this association may be more common than has been previously thought, and the duodenum should be carefully examined in any patient with neurofibromatosis who undergoes laparotomy for pheochromocytoma.
