Gastrointestinal tract is the most common extranodal site involved by lymphoma with the majority being non-Hodgkin type. Although lymphoma can involve any part of the gastrointestinal tract, the most frequent sites in order of its occurrence are the stomach followed by small intestine and ileocecal region. Gastrointestinal tract lymphoma is usually secondary to the widespread nodal diseases and...

Gastrointestinal stromal tumours are the most common mesenchymal neoplasms of gastrointestinal tract. They should be differentiated from other types tumours. GISTs harbour specific activating mutations in KIT or platelet-derived growth factor receptor a (PDGFRA) tyrosine kinases, which makes them responsive to pharmacologic inhibitors. The advances identification GISTs, by its molecular and imm...

We report a case of a metastatic signet ring cell carcinoma (SRCC) of gastrointestinal tract. The case is very rare because gastrointestinal tract SRCC was metastatic to bilateral breasts and ovaries (Krukenberg tumor) in the same young woman almost synchronously under breastfeeding condition. Though the primary site was not detected, IHC results fully verified that the tumor originated from ga...

The gastrointestinal tract of animals is adapted to their primary source of food to optimize resource use and energy intake. Temperate bat species mainly feed on arthropods. These contain the energy-rich carbohydrate chitin, which is indigestible for the endogenous enzymes of a typical mammalian gastrointestinal tract. However, the gastrointestinal tract of bat species should be adapted to thei...

The sonographic evaluation of the gastrointestinal tract regards experienced sonographers who are able to identify all abdominal and parenchymal structures. Transabdominal ultrasonography allows the evaluation of the entire digestive tract, starting with the oesophagus (especially the oesogastric junction), followed by the examination of the stomach, duodenum and small bowel, and ending with th...

Received October 2009 Accepted November 2009 INTRODUCTION A gastrointestinal stromal tumor (GIST) is primarily located in the gastrointestinal tract. It is classified as a mesenchymal tumor that shows a CD117 (c-KIT)-positive mesenchymal spindle or epithelioid neoplasm. Tumors outside the gastrointestinal tract that were histologically similar to GISTs and showed immunopositivity for CD117 were...

Zygomycosis is a fulminant infection which usually afflicts patients who are immunocompromised by diabetes mellitus, malignancy or immunosuppressive therapy.l This disease is a rare but highly invasive fungal infection which occurs in organ transplant recipients. 2 Mucormycosis confined to the gastrointestinal tract is an uncommon form of the disease. accounting for only seven percent of al...
