The authors describe the case of a 51-year-old male with Zollinger-Ellison syndrome manifested by epigastralgia, nausea, vomiting, hypergastrinemia and multiple endocrine neoplasia type 1. History included a Billroth II procedure for a perforated duodenal ulcer. Multiple metastatic liver lesions
OBJECTIVE
To report the case of a patient with multiple endocrine neoplasia type 1 (MEN 1) syndrome with con-comitant parathyroid carcinoma and a classic MEN1 germline mutation.
METHODS
We present the clinical findings, laboratory results, imaging studies, and surgical histopathologic features in a
OBJECTIVE
To describe a novel germline missense mutation in exon 2 of the MEN1 gene identified in a man with multiple endocrine neoplasia type 1 (MEN 1).
METHODS
We describe the patient's clinical, laboratory, and genetic data, and we review the relevant literature.
RESULTS
A 41-year-old man with a

Multiple endocrine neoplasia type 1 (MEN1) is a rare, autosomal dominant inherited syndrome caused by mutations in the MEN1 tumor suppressor gene. The diagnosis is defined clinically by the presence of 2 or more primary MEN1 tumors (parathyroid, anterior pituitary, and pancreatic islet).
A large cell neuroendocrine carcinoma (LCNEC) of the stomach is very rare. A 76-year-old Japanese man was admitted to our hospital because of epigastralgia and nausea. Endoscopy revealed 2 large tumors in the stomach. He did not have multiple endocrine neoplasia type I or Zollinger-Ellison syndrome.
BACKGROUND
Pancreatic endocrine tumors (PETs) are rare and can occur as part of neurofibromatosis type 1 (NF1). Gastrinomas are functional PETs that are rarely associated with NF1. Only two cases of their occurrence have been reported in the literature.
METHODS
A 28-year-old woman was admitted for
Background. Management of multiple-endocrine neoplasia type 1- (MEN1-) associated hyperparathyroidism is associated with high recurrence rates and high surgical morbidity due to multiple neck explorations. Cinacalcet, a calcimimetic agent licensed for the treatment of secondary hyperparathyroidism
BACKGROUND
The management of multiple endocrine neoplasia, type 1 (MEN-1) pancreatoduodenal neuroendocrine neoplasms (NENs) is controversial. An aggressive surgical approach is intended to control the functional syndromes and malignant potential for nodal or distant metastasis.
METHODS
The results
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant endocrine tumour syndrome characterised by three main manifestations: primary hyperparathyroidism (78-94%), gastroenteropancreatic neuroendocrine tumours (GEP-NETs) (35-78%) and pituitary adenomas (20-65%). For metastatic and
Hypercalcemia in a patient with Graves disease can occur in up to 22% of cases. The mechanism is thought to be increased bone resorption. There are more rare causes of hypercalcemia in these patients with hyperthyroidism, such as hyperparathyroidism, which occurs in less than 1% of The role of operation in patients with Multiple Endocrine Neoplasia Type 1 (MEN-1) and Zollinger-Ellison Syndrome (ZES) is controversial. Our institutional bias for this disease has, in general, been towards aggressive imaging and operative removal of localized gastrinomas. Few studies have reported
In this article we reported a female patient with type 2 gastric neuroendocrine tumor (NET). The patient developed upper abdominal pain, acid reflux, heartburn, nausea, and vomiting without obvious cause 16 years ago. Later, a tumor was found in her stomach. Two years ago, a solid mass was found at
Primary hyperparathyroidism is the main endocrinopathy associated with Multiple Endocrine Neoplasia type 1 syndrome. Cinacalcet is a calcimimetic agent licensed for the treatment of secondary hyperparathyroidism in patients with end-stage renal disease, and for the reduction of marked hypercalcemia
The parathyroid glands are the main regulator of plasma calcium and have a direct influence on the digestive tract. Parathyroid disturbances often result in unknown long-standing symptoms. The main manifestation of hypoparathyroidism is steatorrhea due to a deficit in exocrine pancreas secretion.
