The diagnosis relies on cytological (cytoplasmic mucin depletion, cellular crowding and pleomorphism, nuclear hyperchromatism, pleomorphism and stratification, increased nuclear:cytoplasmic ratio, and increased mitotic activity) and (...) -

xanthogranulomatous gastritis
18 March 2012Differential diagnosis
A diagnosis of idiopathic granulomatous gastritis is made when non-caseating granulomas are seen and Crohn’s disease and sarcoidosis have been excluded.
Barium granuloma, a rare complication of x ray examination, shows collections of macrophages and multinucleated giant cells filled with granular material.
Hyalinoid giant cell gastritis is characterised by eosinophilic hyalinoid degeneration of smooth muscle which elicits a giant cell granulomatous reaction. (...) -

colorectal hypersecretory adenoma
13 March 2012Secretory adenoma represents a special variant of villous adenoma, usually arising in the rectum.
Patients present with profuse watery diarrhea, severe fluid and electrolyte loss, elevated blood urea nitrogen, reduced serum sodium, and hypokalemia due to hypersecretion of fluid and an electrolyte-rich mucus.
These abnormalities return to normal once the adenoma is excised.
Characteristically, the mucous diarrhea is most severe in the morning after the stool has accumulated during sleeping (...) -
hemodialysis-associated telangiectasia
12 March 2012Hemodialysis-Associated Telangiectasias
Telangiectasia generally refers to the dilation of pre-existing vessels, whereas angiomatosis refers to new vessel growth.
Gastric telangiectasias develop in some patients on long-term hemodialysis.
The telangiectatic areas appear small, flattened, and reddish with fern-like margins.
Several factors may predispose to its development.
Chronic sodium and water overload may result in venous hypertension, causing submucosal venous dilation. (...) -
caliber-persistent artery
12 March 2012Caliber-Persistent Artery (Dieulafoy Lesion)
The entity variously termed caliber-persistent artery, cirsoidaneurysm, or Dieulafoy lesion tends to affect middle-aged and elderly men.
Median patient age is 52 to 54 years,with patients ranging in age from 16 to 91.
The disorder presents as recurrent, massive, and sometimes fatal hematemesis.
Massive hemorrhage and rupture occur whena large submucosal artery impinges on the mucosa while pursuing its tortuous course through the submucosa. (...) -
gastric angiodysplasia
12 March 2012Patients with angiodysplasia present with overt gastrointestinal bleeding or anemia.
Bleeding from the lesions can be massive and recurrent.
If the lesions are visible endoscopically, they appear bright red, flat,and well circumscribed, or fern-like.
Selective arteriography is the preferred way to establish the diagnosis.
Controversy surrounds the etiology of angiodysplasia.
Arguments favoring an acquired origin include its association with aortic stenosis, underlying inflammatory (...) -
gastric antral vascular ectasia
12 March 2012Gastric Antral Vascular Ectasia (Watermelon Stomach)
Gastric antral vascular ectasia (GAVE) differs from PHG inits clinical features, gross appearance, and histologic features.
However, both conditions are common to patients with cirrhosis.
GAVE presents clinically with bleeding and typically affects elderly females with an average age of 66.5 years.
GAVE associates with various conditions, including cirrhosis, chronic heart disease, bulimia, bone marrow transplantation, and autoimmune (...)
