BACKGROUND Adenocarcinomas of the oesophagus and proximal stomach are the most rapidly increasing malignancies in some countries; however, there are no comparative studies on global disease incidence, and the relationships between these two malignancies are undefined. METHODS We evaluated the cumulative rates and age-specific incidence rates per 100 000 population for adenocarcinomas of the o...

BACKGROUND In western societies, the prevalence of adenocarcinoma of the gastroesophageal junction has increased in recent years. It is commonly accepted today that esophageal adenocarcinoma develops from a premalignant lesion: Barrett's esophagus. This type of carcinoma is hardly diagnosed at early stages, which results in significant mortality. Molecular biology studies have shown that most m...

RATIONALE Primary squamous cell carcinoma (SCC) of the stomach is a rare disease. The pathogenesis and prognosis of advanced SCC remains to be elucidated. The aim of the current study was to investigate the prognosis of recurrent or metastatic SCC of the stomach. PATIENT CONCERNS A retrospective study examined the clinical characteristics and survival outcomes of 14 patients diagnosed with re...

OBJECTIVE To report a rare case of synchronous marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) signet ring cell carcinoma occurring as a collision tumour in the stomach. CLINICAL PRESENTATION AND INTERVENTION A 53-year-old man was diagnosed initially with signet ring cell carcinoma of the stomach. The microscopy of the subsequent total gastrectomy revealed a collision tumou...

Bezoars are concretion of undigested material found in the upper alimentary tract, particularly the stomach. Physiologic disturbances such as gastrointestinal dysmotility or anatomical derangements have been described as contributory in most cases of pharmacobezoars. Gastric phamacobezoars can be treated with endoscopic fragmentation or surgery. Gastric lavage with carbonated beverage has been ...

A composite glandular/exocrine-endocrine carcinoma of the gastrointestinal tract is characterized by the co-existence of two adjacent, but histologically-distinct tumors in an organ. Composite glandular/exocrine-endocrine carcinomas are a special type of tumor comprised of common adenocarcinomas and neuroendocrine components that account for at least one-third of the entire tumor area. Composit...

Hyperplastic polyps are lesions that are mostly smaller than 1 cm; they are sessile and innocuous. They develop as a result of tissue damage and an exaggerated mucosal regeneration. Intestinal metaplasia and dysplasia at a rate of 1–20% may be seen in hyperplastic polyps. However, the risk of carcinoma development is less than 2%. The risk increases in multiple polyps (1). Here we present a cas...

Synchronous occurrence of epithelial and gastrointestinal stromal tumors (GISTs) in the stomach is uncommon. This association has often been detected incidentally on gastric mucosa or serosa, or occasionally intramurally, at surgery or gastroscopy for other reasons. Various hypotheses have been proposed regarding this simultaneous development, and it is not known whether or not such an associat...

The synchronous occurrence of primary renal cell carcinoma with gastric cancer is very rare. We report a case of 41 year old male who presented on 05/07/2011 to M S Ramaiah hospital, Bangalore with history of fever, pain abdomen and malena. Ultrasound abdomen and pelvis showed large heterogenous mass arising from the upper pole of left kidney. Computed tomography of the abdomen showed left rena...

We report two cases of prostate carcinoma metastatic to the stomach. In the first case, the patient had indolent disease before presenting with gastric metastasis. The patient responded to treatment with resolution of gastrointestinal bleeding and other symptoms. In the second case, the patient developed aggressive prostate carcinoma while on immunosuppressive therapy following kidney transplan...
