Gastrinoma, an infrequent diagnosis in middle-aged dogs, occurs with nonspecific gastrointestinal morbidity. Laboratory tests can yield a presumptive diagnosis, but definitive diagnosis depends on histopathology and immunohistochemistry. We describe a malignant pancreatic gastrinoma with lymph node
We saw a 54-year-old patient who had been treated for gastrointestinal ulcerations with bleeding complications now presenting with nausea, vomiting and diarrhoea. The patient has been suffering from recurrent diarrhea for years. The suspicion of a neuroendocrine tumor had been made but could not be
Zollinger-Ellison syndrome is characterized by elevated levels of serum gastrin associated with increased gastric acid secretion, gastrointestinal ulcerations and diarrhea. Most gastrinomas (75%) occur sporadically and are located within the gastrinoma triangle. Extraduodenal, extrapancreatic and
Gastrinoma when associated with liver metastasis results in markedly reduced survival. However, a standard chemotherapeutic protocol for patients with unresectable tumors has not been established. We treated two patients with gastrinoma with multiple liver metastases with intravenous administration
BACKGROUND
A 64-year-old woman presented to the emergency room with a 3-month history of intermittent abdominal cramps, accompanied by nausea, vomiting, anorexia, and decreased bowel movements consistent with a partial intestinal obstruction. She had a 12-year history of peptic ulcers, which had
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
Twenty-one patients with liver metastasis of gastrinoma received intravenous streptozotocin (STZ: 500 mg/sqm.day) and 5 fluorouracil (5 FU: 400 mg/sqm.day) during 5 consecutive days every 6 weeks. Variations in tumor mass (TM) on CT scan and in serum gastrin levels were assessed every two courses.
Forty-two year-old woman, with no relevant medical history, presented with 3-year burning epigastric pain radiating to right upper quadrant, accompanied by nausea and vomiting, food intolerance and estheatorrea. She was treated by 2 years with H2 blockers. Cholelithiasis was found and laparoscopic
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
The value of sequential percutaneous hepatic artery embolization with polyvinyl alcohol particles was examined in 22 patients with islet cell carcinoma metastatic to the liver. Nine patients had gastrinoma, 2 had glucagonoma, and 11 had no discernible hormonal secretions or syndromes. Ninety-seven
We present a case of an 18-year-old male who presented with complains of abdominal pain, nausea and vomiting for 2 years. An esophagogastroduodenoscopy (EGD) revealed a 3 mm nodule on the lesser curvature of the stomach and prominent gastric folds. Biopsy of the nodule revealed a well-differentiated
Zollinger-Ellison syndrome (ZES) is a rare clinical disorder, characterized by hypersecretion of gastric acid and multiple ulcers distal to the duodenal bulb. This occurs via the release of gastrin by neuroendocrine tumors known as gastrinomas. Patients with ZES present with nonspecific GI symptoms,
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
UNASSIGNED
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).
