multiple endocrine neoplasia type 2b/abdominal pain

Alimentary tract manifestations were found in all of 17 patients with multiple endocrine neoplasia, type 2b. The manifestations are important because (1) they were chronic, (2) they were severe and led to abdominal operation in 5 patients, (3) they antedated detection of the endocrine neoplasms in

We present a case of MEN 2B diagnosed in a 23 year-old patient on the basis of bilateral pheochromocytoma and medullary thyroid carcinoma. This young male patient also had multiple paragangliomas located along the spine, marfanoid features of body habitus and numerous mucosal neuromas of the oral

Multiple endocrine neoplasia syndromes (MEN) are genetic disorders with glandular hyperplasia and consecutive malignant neoplasia. MEN type 2B is the least common form of these tumor syndromes. It presents with typical dysmorphic features, mucosal neuromas, ganglioneuromatosis, medullary thyroid

We present a 15-year-old female patient with medullary thyroid carcinoma, marfanoid habitus, and mucosal ganglioneuromatosis. Our case had a RET protooncogene mutation ser836 polymorphism in exon 14 and ser904 polymorphism in exon 15. Our patient is thought to be atypical MEN2B due to the absence of

BACKGROUND Gastric neuroendocrine tumors correspond to less than 1% of all gastric tumors. These tumors can be of three types. Seventy five percent are type I and are associated to chronic atrophic gastritis type A (CAG-A). Half of them are associated with pernicious anemia. Type II tumors are

BACKGROUND Laparoscopic adrenalectomy has gained favour as a preferred surgical approach in the multiple endocrine neoplasia (MEN) type 2 patients. Currently, there is limited literature on bilateral simultaneous laparoscopic adrenalectomy in MEN 2 syndrome. We reported two cases of bilateral

We report a case of neuronal hypertrophy associated with acute appendicitis in which significant neuronal fibers and the number of ganglion cells increased in the absence of inflammatory cells. Differential diagnosis from diffuse ganglioneuromatosis by the pathologic findings of resected specimen

A 58-year-old female with a recurrent history of upper abdominal pain and intermittent dysphagia underwent endoscopic evaluation that demonstrated an irregular and nodular esophago-gastric (EG) junction and grade I erosive esophagitis. Biopsies showed prominent intestinal metaplasia of Barrett's

BACKGROUND Neurogenic appendicopathy is not a very well-known disease. OBJECTIVE To analyze the experience in the management of neurogenic appendicopathy in a tertiary hospital, assessing its clinical presentation, histological staging, the treatment carried out and its clinical

Isolated neurofibromas that affect the gastrointestinal tract are rare and almost always manifest as neurofibromatosis type 1 or multiple endocrine neoplasia type 2b. In this paper, we present a case of a 24-year-old female with abdominal pain who discharged a neurofibroma in her stool without any

Ganglioneuromas (GNs) are hamartomatous tumors derived from the autonomic nervous system. GNs are frequently associated with neurofibromatosis-1 and multiple endocrine neoplasia type 2b and commonly present with constipation, abdominal pain, weight loss, obstruction, and gastrointestinal bleeding.

OBJECTIVE To determine the clinical features, natural history, and role of surgery for gastrointestinal manifestations of the multiple endocrine neoplasia type 2 (MEN 2) syndromes. BACKGROUND The MEN 2 syndromes are characterized by medullary thyroid carcinoma and other endocrinopathies. In
