background: cancer has a high mortality rate in both developing and developed countries. 11%–15% of cancers are attributable to occupational risk factors. objective: to determine if specific occupational classes, based on the international standard for classification of occupations 2008 (isco-08), are risk factors for gastrointestinal (gi) cancer. methods: in this case-control study, 834 cancer...

Purpose. Gastrointestinal tract is one of the rare locations for breast cancer metastasis. This paper shows such metastasis may occur even in the absence of breast metastasis in other more common locations. Case Report. A 64-year old female was admitted to the hospital with abdominal discomfort and diarrhea. She had breast carcinoma treated 7 years previously with normal follow-up since. Colono...

ingestion of foreign bodies is common and conservative treatment can eliminated most particlesfrom the gastrointestinal tractunless peritoneal signs appear. a 22-year-old man presented to emergency department who had ingested glass particles of a crushed beverage bottle. he complained of epigastric and periumbilical pain. physical examination did not revealany peritoneal signs. abdominal x-ray ...

introduction: accurate diagnosis and proper treatment of oncology patients presented to emergency department (ed) can dramatically enhance their quality of life and decrease their mortality rate. therefore, the present study aimed to evaluate these patients from an epidemiologic point of view as well as identifying death-related factors. methods: in this retrospective cross-sectional study, all...

  Gastrointestinal aspergillosis most often occurs in the setting of disseminated infection from a primary pulmonary site and primary gastrointestinal aspergillosis is an unusual presentation. We report a 7 year old female child with aplastic anemia, who was under treatment but experienced periods of neutropenia. She had no evidence of respiratory aspergillosis before the onset of abdominal s...

background : although, family history of cancer is an important risk factor for upper gastrointestinal cancers development, but limited information is available on the upper gastrointestinal cancers associated with family history in iran. the purpose of this study was to define upper gastrointestinal cancers risk associated with family history of cancer. methods : this study was conducted as a ...

A rare case of diffuse lymphomatous polyposis of the gastrointestinal tract is reported in which the patient presented with abdominal pain, weight loss and bloody diarrhea. X-rays revealed multiple polyps involving the stomach, small intestine and colon. Biopsies confirmed the diagnosis of lymphomatous polyposis. The duration of symptoms and signs was 3 months. Diffuse lymphomatous polypos...

It is well established that cancer arises in chronically inflamed tissue, and this is particularly notable in the gastrointestinal tract. Classic examples include Helicobacter pylori-associated gastric cancer, hepatocellular carcinoma, and inflammatory bowel disease-associated colorectal cancer. There is growing evidence to suggest that this association is not coincidental but may indeed be cau...

Although the majority of mesenchymal lesions of the gastrointestinal tract are neoplastic in nature, but nonneoplastic reactive processes may also involve the gastrointestinal tract and mesentery. Some more aggressive neoplasms located in same area, such as fibromatosis or gastrointestinal stromal  tumors  may  be  cause  of  diagnostic  confusion.  Reactive  nodular  fibrous  pseudo  tumor (RN...

Chronic inflammation has been identified as an important risk factor for the development of malignancy, and knowledge about its molecular and cellular mechanisms is increasing. Several chronic inflammatory diseases of the gastrointestinal tract are important as risk factors for malignancy and have been studied in detail. In this review, we summarize important molecular mechanisms in chronic inf...
