Cardiac mass can be described as an abnormal structure within or directly contiguous to the heart. Tumors and thrombi are the most common types of cardiac masses. Intracardiac thrombi have been encountered in various clinical settings and can result in severe morbidity and mortality due to embolic events. Cardiac neoplasms are extremely rare, and are usually metastatic tumors. The major primary malignancies associated with cardiac metastases include cancers of the lung, breast, stomach, and liver, and lymphoma, leukemia, and melanoma...

Neutrophil gelatinase-associated lipocalin, known also as 24p3 lipocalin, lipocalin-2 or uterocalin (in mouse), is a small secretory protein binding small molecular weight ligands which takes part in numerous processes including apoptosis induction in leukocytes, iron transport, smell, and prostaglandins and retinol transport [19]. It was discovered in activated neutrophils as a covalent peptide associated with human gelatinase neutrophils [7]. Neutrophil lipocalin is secreted physiologically in the digestive system, respiratory tract, renal tubular cells, liver or immunity system...

Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms that arise in the gastrointestinal tract, accounting for ~1% of gastric malignancies. The present study reports the case of a GIST of the stomach in a 75-year-old man who presented with abdominal distension and anorexia for 1 month. Gastroscopy was unremarkable. Ultrasound and computed tomography (CT) scans showed a giant intraabdominal cystic lesion of unknown origin. The lesion was initially believed to be a duplication cyst, a pancreatic pseudocyst or a liver cyst in the pre-operative diagnosis...

INTRODUCTION: Gastrointestinal stromal tumor (GIST) is the commonest mesenchymal tumor of GI tract and 60-70% of it seen in the stomach, whereas Gastric schwannoma is a benign, slow growing and one of the rare neoplasms of stomach. Age distribution, clinical, radiological features and gross appearance of both tumors are similar. PRESENTATION OF CASE: We report a rare case of gastric schwannoma in a 20-year-old girl, who underwent subtotal gastrectomy with the suspicion of a GIST preoperatively but later confirmed to be gastric schwannoma postoperatively after immunohistochemical study...

Mixed adenoneuroendocrine carcinomas (MANECs) are composite neoplasms with areas of adenocarcinoma or squamous cell carcinoma intermingled with neuroendocrine carcinoma or neuroendocrine tumor, each composing at least 30% of the neoplasm. MANECs are very infrequent overall, and they are more commonly diagnosed in the appendix, colon, and stomach. Biliary MANECs are particularly rare, and their histogenesis is debated because neuroendocrine cells are seldom identified in the normal biliary tract. They can show one of the 3 different architectural patterns described in Lewin's original classification: collision tumors, combined lesions, or amphicrine neoplasms...

AIM: To describe a series of patients with aberrant polypoid nodule scar developed after gastric endoscopic submucosal dissection (ESD), and to discuss its pathogenesis and clinical management. METHODS: We reviewed retrospectively the endoscopic database of two academic institutions located in Brazil and Japan and searched for all patients that underwent ESD to manage gastric neoplasms from 2003 to 2015. The criteria for admission in the study were: (1) successful en bloc ESD procedure with R0 and curative resection confirmed histologically; (2) postoperative endoscopic examination with identification of a polypoid nodule scar (PNS) at ESD scar; (3) biopsies of the PNS with hyperplastic or regenerative tissue, reviewed by two independent experienced gastrointestinal pathologists, one from each Institution...

INTRODUCTION: Extramedullary plasmacytoma (EMP) is a plasma cell neoplasm that presents as a solitary tumor. EMP in the gastrointestinal organs are extremely uncommon. PRESENTATION OF CASE: A 36-year-old man was admitted to our hospital with advanced anemia. He had no specific medical history. Gastroendoscopic findings showed an 8.0-cm submucosal tumor with ulcer on the greater curvature of the gastric body. Fine-needle aspiration was performed, and the pathologic diagnosis of the submucosal tumor was a plasmacytoma...

Primary gastric chorioadenocarcinoma (PGC) is a rare and rapidly invasive tumor. Choriocarcinoma is usually known to be of endometrial origin and gestational; however, it has been reported in other extragenital organs, such as the gall bladder, prostate, lung, liver, and the gastrointestinal tract. Human chorionic gonadotropin related neoplasms of the stomach are seldom discussed in the literature. We report a case of PGC in a 56-year-old man treated with a standard non-gestational choriocarcinoma chemotherapy regimen, EMA/CO (etoposide, methotrexate, actinomycin D, cyclophosphamide, vincristine), with a complete response and good tolerability...

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a heterogeneous group of tumors deriving from the gastrointestinal (GI) neuroendocrine system. Since these neoplasms are usually very small, located deeply within the retroperitoneum or into an extramucosal site of the GI tract and, lastly, because they may be multi-sited, radiological imaging modalities, in combination with endoscopy, are the diagnostic workhorses in patients with GEP-NETs. Endoscopic approach is useful for detection, bioptic diagnosis and curative resection of small GEP-NETs of stomach, duodenum, jejuno-ileum, and colon-rectum...

INTRODUCTION: MALT lymphoma accounts for 7-8% of all B-cell lymphomas and at least 50% of primary gastric lymphoma, with the highest incidence at between 50 and 60 years of age. Aggressive forms are rare, as are indications for multi-visceral resection. CASE STUDY: A patient, 33 years old, was admitted to the tertiary hospital due to a biopsy at a small community hospital confirming adenocarcinoma of the stomach. She was Helicobacter pylori positive. CT showed thickening of the fundus and corpus wall, up to 2...

: The duodenum is a short segment of the bowel that is frequently overlooked on radiologic examination. This unique portion occupies both intraperitoneal and extraperitoneal locations, with proximity to many visceral organs, including pancreas, stomach, aorta, and liver. This close proximity creates a differentiation challenge for the radiologist. Duodenal pathologies are categorized into neoplastic and nonneoplastic conditions. Majority of radiologists are familiar with duodenal neoplasm...

Gastric carcinoma (GC) is the most common neoplasm in the stomach of dogs. Although incidence in the general population is reported to be low, breed-specific GC has a high incidence. Median age at presentation ranges from 8 to approximately 10 years. The disease is mostly located in the lesser curvature and antropyloric region of the stomach. Unfortunately, diagnosis is usually made when the disease is at an advanced stage and, therefore, prognosis is poor. Due to similarities in clinical presentation, diagnosis, histology and prognosis, canine GC may serve as a valuable model for human GC...

Small cell neuroendocrine carcinoma (SNEC) is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach...

In 2012, gastric cancer (GC) was the third cause of mortality due to cancer in men and women. In Central and South America, high mortality rates have been reported. A total of 95% of tumors developed in the stomach are of epithelial origin; thus, these are denominated adenocarcinomas of the stomach. Diverse classification systems have been established, among which two types of GC based on histological type and growth pattern have been described as follows: Intestinal (IGC) and diffuse (DGC). Approximately 1-3% of GC cases are associated with heredity...
