PURPOSE OF REVIEW: Neuroendocrine tumors (NETs) were initially identified as a separate entity in the early 1900s as a unique malignancy that secretes bioactive amines. GI-NETs are the most frequent type and represent a unique subset of NETs, because at least 75% of these tumors represent gastrin stimulation of the enterochromaffin-like cell located in the body of the stomach. The purpose of this review is to understand the specific role of gastrin in the generation of Gastric NETs (G-NETs)...

Carcinoid tumors are rare neuroendocrine tumors that have been reported in a wide range of organs but most commonly involve the gastrointestinal tract (stomach, ileum, appendix, and colon), and rarely ovary and thymus. We present a case of a 56-year-old Nigerian man with a cecal carcinoid tumor that was surgically removed. A 56-year-old Nigerian man, presented to our hospital with a year history of right-sided lower abdominal fullness, audible bowel sounds, occasional diarrhea, nausea, vomiting, and epigastric pain...

Metastatic neoplasms of unknown primary site pose a major challenge to patient management. As targeted therapies are now being tailored to neuroendocrine tumors (NETs) of different primary sites, identifying the origin of metastatic NETs has become increasingly important. Compared with more extensive efforts on metastatic adenocarcinomas of unknown primary, the literature on metastatic NETs (often to the liver) is relatively sparse and most studies are based on primary tumors. We sought to study metastatic well-differentiated NETs to the liver to identify markers that predict the site of origin...

We report a unique case of synchronous double primary gastric cancer consisting of adenocarcinoma components with micropapillary features and composite glandular-endocrine cell carcinoma components. The patient was a 53-year-old man presenting with a 6-month history of epigastric pain and diarrhea. A subtotal gastrectomy was performed. Histologically, one tumor was composed of micropapillary carcinoma components (50%) with tight clusters of micropapillary aggregates lying in the empty spaces, admixed with moderately differentiated adenocarcinoma components...

Multiple Endocrine Neoplasia (MEN) is a condition in which several endocrine organs of an individual are affected by adenoma, hyperplasia and less often carcinoma, either simultaneously or at different stages of life. Two existing syndromes, MEN1 and MEN2 (2A, 2B), in literature is also mentioned MEN4, are associated also with other non-endocrine disorders. MEN1 (Wermer syndrome) affects the pituitary, parathyroid, and pancreatic area. 95 % of patients show very early manifestation of hyperparathyroidism, often before 40 years of age...

Dear Editor, Scleroderma associated with neoplasia is rare, with only a small number of cases reported. We describe 4 patients with paraneoplastic scleroderma who were treated at the I. Department of Dermatovenereology, St. Anna Hospital, during the period between 2004 and 2014. The patients were diagnosed with cholangiogenic carcinoma, endometrial carcinoma, prostatic adenocarcinoma, and adenoma of the suprarenal gland. In the case of concurrent scleroderma and tumor, four situations may occur: they can develop independently of each other; scleroderma may be induced by the tumor; the tumor can develop in the scleroderma; or the tumor can be induced by immunosuppressive therapy...

Comparative study of plasma chromogranin A levels was carried out in 227 patients with neuroendocrine tumors of various locations and 66 normal subjects, men and women, by standard ELISA. In patients with tumors of all locations (pancreas, stomach, small and large intestine, and lungs), the glycoprotein levels were significantly (p<0.000001) higher than in controls. The patients demonstrated high variability of chromogranin A levels; the maximum concentrations were detected in patients with neuroendocrine tumors of the stomach and lung...

Autoimmune polyglandular syndrome by definition consists of two or more endocrinological insufficiencies or two organ specific autoimmune diseases. There are no stringent criteria for endocrinological evaluation of patients with one endocrine insufficiency. However, detailed endocrinological evaluation should be undertaken in patients with two autoimmune diseases. Additionally, follow up thereafter should be a must in these patients in order to avoid the possibility of not diagnosing subsequent autoimmune diseases that can occur...

The expression of cholecystokinin 2 receptor (CCK2R, CCKBR or gastrin receptor) has been reported on a diverse range of cancers such as colorectal, liver, lung, pancreatic, ovarian, stomach, thyroid and numerous neuroendocrine/carcinoid tumors. Some cancers of the colorectum, lung, pancreas and thyroid have been shown to overexpress CCK2R in relation to normal matched tissues of the same organ. This reported overexpression has led to the development of a number of CCK2R-ligand targeted imaging and therapeutic agents...

Jin Woong Cho
Subepithelial tumors are frequently found in asymptomatic patients in Japan and Korea where cancer screening tests routinely include endoscopy. Most lesions are asymptomatic and clinically insignificant. However, carcinoid tumors, lymphomas, glomus tumor and gastrointestinal stromal tumors (GISTs) are malignant or have the potential to become malignant. Inflammation due to parasitic infestation by Anisakis and poorly differentiated adenocarcinomas in the stomach rarely present as subepithelial lesions. In contrast to the frequency of gastric GIST in the gastrointestinal system, they are uncommon in the duodenum and very rare in the esophagus...

BACKGROUND: Gastric carcinoids are slow growing neuroendocrine tumours arising from enterochromaffin-like (ECL) cells in the corpus of stomach. Although most of these tumours arise in the setting of gastric atrophy and hypergastrinemia, it is not understood what genetic background predisposes development of these ECL derived tumours. Moreover, diffuse microcarcinoids in the mucosa can lead to a field effect and limit successful endoscopic removal. OBJECTIVE: To define the genetic background that creates a permissive environment for gastric carcinoids using transgenic mouse lines...

A 67-year-old man had a gastric polyp diagnosed on screening. Atrophic changes in the upper gastric mucosa were seen on upper gastrointestinal endoscopy. In addition, endoscopy revealed in the middle area of the stomach wall a 10 mm polyp that was diagnosed as a carcinoid tumor through biopsy. Blood serum gastrin was elevated at 2,800 pg/mL.We diagnosed a Rindi Type 1 gastric carcinoid. The patient was planned to be treated with surgical laparoscopy assisted distal gastrectomy (LADG); however, the procedure was changed to intraoperative laparoscopy assisted total gastrectomy (LATG)...

Gastroenteropancreatic (GEP) endocrine tumours (carcinoids and pancreatic islet cell tumours) are composed of multipotent neuroendocrine cells that exhibit a unique ability to produce, store, and secrete biologically active substances and cause distinct clinical syndromes. The classification of GEP tumours as functioning or non-functioning is based on the presence of symptoms that accompany these syndromes secondary to the secretion of hormones, neuropeptides and/or neurotransmitters (functioning tumours). Non-functioning tumours are considered to be neoplasms of neuroendocrine differentiation that are not associated with obvious symptoms attributed to the hypersecretion of metabolically active substances...

INTRODUCTION: Heterotopic pancreas is defined as pancreatic tissue without a real anatomical or vascular connection to the pancreas. It can be found in the stomach, duodenum, jejunum, ileum, Meckel's diverticulum, colon gall bladder, umbilicus, fallopian tube, mediastinum, spleen and liver. Complications of heterotopic pancreas are inflammation, bleeding, obstruction, malignant transformation, carcinoid syndrome, jejunojejunal intussusception and ileus, but it is usually asymptomatic and diagnosed only during examinations for other diseases...

An 80-year-old woman was treated with low anterior resection and D3 lymph node dissection for rectal carcinoid in August 2007. Pathological diagnosis was a tumor 23 × 22 mm in size with muscularis propria invasion, ly1, v0, n1 (No. 251[1/12]). Partial hepatectomy was performed for liver metastasis in March 2010 and September 2011. In June 2013, an isolated tumor of 17 mm in diameter was detected between the inferior vena cava and the stomach using abdominal ultrasonography. The tumor was diagnosed as pancreatic head lymph node metastasis using abdominal enhanced computed tomography (CT), magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET); fluorodeoxyglucose (FDG) uptake was noted at the site of the tumor, but not at other parts of the body...
