Lymphoepithelioma-like gastric carcinoma presenting as giant ulcer of the lesser curvature. Case report

Lymphoepithelioma-like gastric carcinoma (LELGC) has special clinicopathologic features that differentiate it from the common gastric adenocarcinoma. LELGC is a rare neoplasm of the stomach with an incidence of 1-4% of all gastric cancers and is characterized by desmoplastic stroma uniformaly infiltrated by abundant lymphocytes and plasma cells. LELGC is closely associated with the Epstein-Barr virus (EBV), with 80-100% of LELGC being EBV-positive. LELGC has a male predominance, occurs in elderly people and is usually located in the upper and middle portion of the stomach. We report a rare case of lymphoepithelioma-like gastric carcinoma located in the lesser curvature at the border of the gastric body to the pyloric antrum.

Laparoscopic treatment of mucinous adenocarcinoma of jejunum associated with celiac disease. Case report

Mucinous adenocarcinoma of the small bowel is very rare, and only few cases have been described in the literature. Association of this tumor with celiac disease has never been published. The authors report a unique case of jejunal mucinous adenocarcinoma in which a concomitant celiac disease has been histologically recognized. The difficult diagnosis, the role of laparoscopic surgery and the relationship between small bowel tumors and celiac disease are discussed. A 49-year-old man presented with recurrent melena, nausea, vomiting and anemia. A stenosis of the jejunum was documented by means of CT scan and video capsule enteroscopy. A laparoscopy was scheduled. A tumor, found in the first jejunal loop, was removed by laparoscopic surgery. Histopathology revealed a rare mucinous adenocarcinoma associated with epithelial changes secondary to celiac disease. Although small bowel tumors are rare entity, in patients with celiac disease complaining of symptoms related to altered intestinal transit or occult bleeding, an appropriate work-up should be planned for diagnosis. Mucinous type intestinal adenocarcinoma, even if never published before, could be observed. Laparoscopic surgery is often essential for the diagnosis and treatment.

Complications after laparoscopic Roux-en-Y gastric bypass: a diagnostic challenge. Report of three cases and review of the literature

The number of Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) procedures for morbid obesity and type 2 diabetes mellitus will increase worldwide, and therefore, an increase in perioperative morbidity can be anticipated. The authors present three cases based on different complications after LRYGB to demonstrate the diagnostic challenge that clinicians face in this particular group of patients. Also, a review of the literature covering the value of different imaging in these particular cases is provided by the authors. The role of imaging in the diagnostic process is discussed.

Small bowel adenocarcinoma. Two case reports

Introduction. Small bowel adenocarcinoma is a rare tumor, with a still not well studied tumorigenesis process, and non-specific symptoms that cause a delay in the diagnosis and consequently a worst outcome for the patient. Videocapsule endoscopy (VCE) and double-balloon enteroscopy (DBE) have revolutionized the diagnosis and management of patients with small bowel diseases. Surgery is the treatment of choice when feasible, while the chemotherapeutic approach is still not well standardized. Case reports. Two cases in 2 months (two women 52 and 72-yr-old) of primary bowel adenocarcinoma is reported. The site of the tumor was in jejunum, instead of the most common site in duodenum. The patients underwent DBE with biopsy and ink mark. Laparoscopic-assisted bowel segmental resection was performed. The pathologic diagnosis was primary jejunum adenocarcinoma. No post-operative mortality or significant morbidities were noted. Conclusion. The combination of DBE and laparocopic-assisted bowel surgery represents an ideal diagnostic and therapeutic method.

Laparoscopic-endoscopic rendez-vous resection of iuxta-cardial gastric GIST

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract and they often require a surgical removal. Gastrointestinal stromal tumors can originate from any part of the gastrointestinal tract but gastric location is the most common. In the past the risk of rupture of pseudocapsula and peritoneal dissemination have discouraged surgeons from making a minimally invasive surgical treatment. Recently laparoscopic wedge resection has been proposed. Performance of this mini-invasive technique is however difficult in some gastric location of gastrointestinal stromal tumors, such as iuxta-cardial region. The Authors report and discuss a new technique they used to remove a gastrointestinal stromal tumor located just below the cardia, using a rendez-vous endoscopic and laparoscopic technique.

Valutazione di effetti citotossici ed emolitici di peptidi ad attività antimicrobica su cellule umane mononucleate del sangue periferico (PBMC) e sulla linea cellulare di adenocarcinoma prostatico PC3

Un film edibile è un sottile strato di materiale commestibile, preformato o formato direttamente sull'alimento, usato come rivestimento o inserito tra i diversi componenti dell'alimento stesso. Per le sue peculiari caratteristiche un film edibile è preparato con materiali commestibili e rappresenta una protezione per l'alimento dall'ambiente esterno. É dunque parte integrante dell'alimento, prolungandone la "shelf-life", ovvero il periodo di utilizzo in commercio del prodotto, dunque il tempo utile tra la data di confezionamento e di scadenza. Una maggiore "shelf-life" comporta molteplici vantaggi per tutti i settori coinvolti nella filiera alimentare: chi produce infatti può offrire ai distributori un prodotto con maggiori garanzie di qualità e conservazione, che distribuisce può allungare il periodo di esposizione negli scaffali e di stoccaggio nei magazzini, chi consuma ottiene un prodotto più sicuro e che può essere conservato più a lungo. I film edibili inoltre sono dotati di proprietà peculiari, infatti conferiscono protezione agli alimenti, costituendo un'interfaccia tra prodotto e ambiente e rallentando il decadimento qualitativo; hanno una natura ecologica perchè non incidono sull'inquinamento ambientale essendo commestibili; sono funzionali, poichè oltre al ruolo di imballaggio, possono assumere funzione antimicrobica e funzionale.

Gastric and Peritoneal Involvement of Human Herpes Virus 8 Related Kaposi Sarcoma in a Patient with Acquired Immunodeficiency Syndrome

Kaposi's sarcoma (KS) is one of the most frequent neoplastic diseases in patients infected with human immunodeficiency virus (HIV). The authors report the case of a 40-year-old male with ascites, peripheral edema and peritoneal carcinomatosis secondary to a gastric KS related to human herpes virus type 8 (HHV-8). The patient had severe immunodeficiency, with a TCD4+ count of 86 cells/µl and newly diagnosed acquired immunodeficiency syndrome. His clinical condition rapidly deteriorated, with multiorgan failure, and he died without the possibility of initiating antiretroviral therapy or chemotherapy. To the authors’ knowledge, carcinomatosis is a rare feature in KS.

An Unexpected Cause of Marked Weight Loss Associated with Vomiting in an Adult Man: Gastric Phytobeozar

Objectives: We present the case of an edentulous 47-year-old farmer referred to our Department of Internal Medicine because of postprandial vomiting, hyporexia, asthenia and weight loss. He ate a mostly vegetarian diet. Materials and methods: An oesophagogastroduodenoscopy revealed the presence of a phytobezoar at the level of the fundus and body of the stomach. Endoscopic fragmentation and removal of the phytobezoar were unsuccessful and the patient had to undergo open surgery. Results: Recovery was uneventful and free of complications. Conclusion: Phytobezoars should be taken into account in the differential diagnosis of unexplained vomiting and weight loss.
