BACKGROUND: Although cases of multiple primary malignant neoplasms are increasing, reports of more than three or four primary metachronous malignant neoplasms are extremely rare. Moreover, very few publications have provided a genetic mutational analysis or have evaluated risk factors associated with such neoplasms. We present an extremely rare case of nine primary malignant lesions in a man who was successfully treated. We also report on microsatellite stability status, analyze risk factors, and discuss the relevant literature...

BACKGROUND: Robotic total pancreatectomy (TP) represents a minimally invasive approach to a major intra-abdominal operation. Its utility, technique, and outcomes are evolving. METHODS: In this video, we describe a systematic approach to a robotic total pancreatectomy performed for multifocal intraductal papillary mucinous neoplasm (IPMN). Additionally, we reviewed the National Cancer Database (NCDB) to examine the outcomes of robotic TP compared to laparoscopic and open TP between 2010 and 2014...

Objective: Neuroendocrine tumors arise from neuroendocrine cells in any part of the body; approximately two thirds of these tumors are located in the gastrointestinal tract and pancreas. Although gastroenteropancreatic neuroendocrine tumors are known as rare neoplasms, their prevalence has recently increased due to advanced diagnostic methods and increased awareness of the disorder. In the present study, we aimed to review patients who were treated and followed up for gastroenteropancreatic neuroendocrine tumors at our clinic in terms of clinical picture, pathological findings, and prognosis...

BACKGROUND AND AIMS: To clarify whether dental floss clip traction improves the technical outcomes of endoscopic submucosal dissection (ESD). METHODS: A superiority, randomized control trial was conducted at 14 institutions across Japan. Patients with single gastric neoplasm meeting the indications of the Japanese guidelines for gastric treatment were enrolled and assigned to receive conventional ESD or dental floss clip traction ESD (DFC-ESD). Randomization was performed according to a computer-generated random sequence with stratification by institution, tumor location, tumor size, and operator experience...

Extra-gonadal choriocarcinoma is an extremely rare highly malignant neoplasm with a poor prognosis. In the gastrointestinal tract it usually arises in stomach, esophagous, bowel intestine and colon. Only few cases are pure and not associated with a classic adenocarcinoma. The correlation of Crohn's disease with choriocarcinoma is not reported. We describe a case of 47-year old man with primary choriocarcinoma of the colon in a previously documented Crohn's disease.

Among the somatostatin analogues, octreotide (OCT) is the most commonly used in clinic via intravenous or subcutaneous injection to treat various diseases caused by increased secretion of growth hormone, gastrin or insulin. In order to assesse the feasibility of developing oral formulations of OCT, we conducted systematical pharmacokinetic and pharmacodynamic analyses of OCT in several animal models. The pharmacokinetic studies in rats showed that intragastric administration of OCT had extremely low bioavailability (<0...

Pulmonary and pleural metastases are routinely identified on thoracic computed tomography. Pulmonary metastases are the most common pulmonary neoplasms and commonly originate from primary malignancies of the lung, breast, colon, pancreas, stomach, skin (ie, melanoma), head and neck, and kidney. Metastatic disease to the lungs may occur via 3 routes of spread: hematogenous, lymphatic, and endobronchial. Pleural metastases most commonly originate from primary malignancies of the lung and breast. Mechanisms of pleural metastatic involvement include hematogenous spread, direct invasion from a neighboring tumor, and retrograde lymphatic spread from the mediastinum...

Gastrointestinal stromal tumors (GISTs) are rare neoplasms, but they also represent the most common mesenchymal tumors of the gastrointestinal tract originating from the cell of Cajal. GIST incidence ranges around 1% of all gastrointestinal malignancies. Approximately 5% of all GISTs have a hereditary etiology. The remaining 95% of GISTs are considered sporadic events, with up to 75% of cases driven by a constitutional activation of the c-KIT proto-oncogene. GISTs are generally solitary lesions. Nonetheless, multiple sporadic GISTs can occur and present as synchronous or metachronous tumors, usually associated with familial GIST...

Gastrointestinal stromal tumor is rare digestive tract mesenchymal tumor, most often in the wall of the stomach. It is a benign neoplasm, but it can become malignant if not treated. We report a case of gastrointestinal stromal tumor that was discovered after abdominal ultrasonography during staging of a patient with primary cutaneous amelanotic melanoma. Mutation in the tyrosine kinase receptor could explain the development of two types of tumors in the same patient.

The Roux-en-Y gastric bypass is one of the most common procedures currently performed for surgical treatment of patients with severe obesity. Gastric cancer after bariatric surgery is not common, with most of them arising in the excluded stomach. Gastric mixed adenoneuroendocrine carcinomas are a rare type of stomach malignancy, composed of both adenocarcinoma and neuroendocrine tumor-cell components, with the latter comprising at least 30% of the whole neoplasm. In this article, we report a unique case of a mixed adenoneuroendocrine carcinoma with a mixed adenocarcinoma (tubular and poorly cohesive) component arising in the gastric pouch of a patient who underwent previous Roux-en-Y gastric bypass for glycemic control...

BACKGROUND: Representative data on the gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) in Asian patients is rare, especially in China. This study aims to create a GEP-NENs profile of Chinese patients. METHODS: This was a hospital-based, nation-wide, and multi-center 10-year (2001-2010) retrospective study which collected GEP-NEN patients' information in tertiary referral hospitals. All 2010 inpatient GEP-NEN cases with confirmed pathology in the selected hospitals were included...

INTRODUCTION: Gastrointestinal stromal tumors (GISTs), originating from Cajal cells, are most commonly located in the stomach; therefore they can be found in the specimens excised during bariatric operations. The global prevalence of GISTs is about 130 cases per million population. Morbidity differs depending on geographical latitude. Although surgery is the treatment of choice for GISTs, 40-50% of patients after radical surgical treatment will have a relapse or metastases. AIM: To analyze the incidence of GISTs in patients undergoing bariatric surgery and to verify whether an operation performed according to the bariatric protocol is oncologically radical in case of GIST...

INTRODUCTION: Duodenal obstructions caused by congenital anatomic abnormalities are rare in adults. Several patients in whom the duodenal obstruction was caused by a congenital duodenal diaphragm have been described. The duodenal obstruction in the patient presented herein was caused by a transverse septum, which has not been previously reported. A transverse septum is usually observed in the vagina; those involving the digestive tract have been rarely observed. CASE PRESENTATION: We herein report a case involving a 69-year-old woman with a congenital duodenal transverse septum causing partial obstruction...

Acinar cell cystadenocarcinoma is a rare malignant epithelial neoplasm of the pancreas with a diffusely cystic, gross architecture in which the cysts are lined with neoplastic epithelial cells that demonstrate evidence of pancreatic exocrine enzyme production. This is the 10th case that has been reported in the literature. A 77-year-old male complaining of left hypochondrial pain was referred to our hospital for treatment of a pancreatic tumor. A huge, honeycomb-structured tumor was detected in the pancreatic tail...

Gastric cancer is an important disease due to its high mortality. Despite the decline in frequency, most cases are discovered late in its course, and most of the cancer patients die within a few years of diagnosis. In addition to Helicobacter pylori gastritis, gastrin is considered an important factor in the development of this disease, and thus, cholecystokinin-B receptor (CCKBR) becomes of interest. The aim of our study was to explore whether CCKBR is expressed in stomach cancers. Thirty-seven tumors from 19 men and 18 women diagnosed with either adenocarcinoma or neuroendocrine neoplasm (NENs) were included in this study...

The ovaries are common site of metastasis in a variety of primary neoplasms. Multiple tumors such as breast, lung, and pancreas have been reported to metastasize to the ovary, however; the colon and stomach are the most common primary cancer sites that of ovarian metastasis. An ovarian mass mostly originates from its self-tissue, but sometimes it can be a metastasis of a gastrointestinal system tumor. Such cases are often misdiagnosed as primary ovarian cancers. A 42-year-old woman was admitted to our hospital with pelvic pain...

Granular cell tumor (GCT) also known as Abrikossoff's tumor is a benign neoplasm that is usually seen in the fourth to sixth decades of life with slight female preponderance. It is most frequently seen in the oral cavity, skin, and subcutaneous tissue. Gastrointestinal tract involvement is uncommon, in which esophagus is the most commonly affected site. There are case reports of GCT in stomach, appendix, colon and rectum. In this article, we report a case of GCT involving cecum. The cell of origin in GCT is controversial...

The diagnosis of neuroendocrine neoplasms (NENs) may be challenging and is based on typical morphological features and positive staining for antibodies of neuroendocrine differentiation. Neuron-specific enolase (NSE) being a cytosolic marker may be useful in this setting. NSE is by many considered nonspecific, due to the finding of this marker in tumors considered not to be of neuroendocrine origin. Our aim was to determine whether this is true and whether NSE is more specific than previously realized. We examined 178 tumors (carcinomas and NENs) from breast, lung, stomach, and kidney using immunohistochemistry with the following markers: chromogranin A, synaptophysin, CD56, secretagogin, and NSE...

Metastatic solid pseudopapillary neoplasms of the pancreas are rare, and the stomach is also a rare site for metastases. We present a case of a lady with solid pseudopapillary neoplasm of the pancreas who previously had a distal pancreatectomy but subsequently had multiple hepatic, adrenal peritoneal and nodal metastases. She developed dyspepsia and on oesophagogastroduodenoscopy, was found to have gastric metastases as well. We believe this is the first reported case of metastatic solid pseudopapillary neoplasm of the pancreas to the stomach...
