Gastric 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 (...)

portal hypertensive gastropathy
12 March 2012congestive gastropathy
Portal hypertensive gastropathy (PHG) is a vasculopathy involving the gastric microvasculature in both adults and children with portal hypertension.
Mild PHG is highly prevalent in cirrhotics,while severe changes are only seen in 10% to 25% of these patients.
The disorder presents with bleeding in severe cases.
A hallmark of the condition is mucosal and submucosal capillary and venous ectasia that insevere PHG imparts a typical mosaic appearance.
The mucosa (...) -
gastric varices
12 March 2012Gastric varices are less common than esophageal varices and affect approximately 20% of patients with portal hyperten-sion, usually accompanying esophageal varices.
Gastric varices typically surround the cardioesophageal junction and they commonly bleed.

gastric inflammatory fibroid polyp
12 March 2012inflammatory fibroid polyp of the stomach
Inflammatory fibroid polyps (IFPs) affect all areas ofthe GI tract.
Most lesions develop in adults, although some occur in children.
The average patient is 63 years old.
IFPs may remain asymptomatic or cause abdominal pain due to gastric outlet obstruction.
The lesions are reactive in nature.
Associated lesions include HP gastritis, gastric ulcer, adenoma, or carcinoma.
Macroscopy
Grossly, IFPs present as sessile, firm, gray-tan polypoid or (...) -
gastric isolated hamartomatous polyp
12 March 2012Microscopy
Isolated hamartomatous polyps consist of a prominent sub-mucosal mass of haphazardly arranged oxyntic glands in a framework of smooth muscle tissue and occasional focal accumulations of mature lymphoid tissue.
The entire lesion is supported by normal lamina propria.
The glands may appear normal or be cystically dilated.
One also sees mucous cells resembling foveolar epithelium as well as rare antral or cardiac-type glands containing endocrine cells indigenous to the mucosal (...) -

A “peptic ulcer”refers to any deep mucosal break resulting from exposure to gastric acid or pepsin.

These ulcers develop adjacent to sites containing oxyntic mucosa.
Rarely, they arise in the acid-secreting mucosa itself.
Peptic ulcers fall into several major etiologic groups
Those resulting from acidhypersecretion,as in Zollinger-Ellison syndrome; (...) -
allergic gastritis
6 March 2012The stomach is commonly involved in food-induced hypersensitivity reactions, especially in children.
Allergic gastritis is usually a manifestation of a more extensive allergic gastroenteritis.
Patients present with anorexia, nausea, vomiting, diarrhea, weight loss, peripheral eosinophilia, elevated serum IgE, a personal or family allergic history, and epigastric pain.
Direct mucosal challenge with a specific antigen in allergic individuals produces gastric mucosal edema, erythema, and (...) -
gastric cancer-associated granuloma
6 March 2012A marked granulomatous gastritis may also complicate gastric malignancies (carcinomas or lymphomas).
The granulomas resemble sarcoid granulomas and may affect all levels ofthe gastric wall or the draining regional lymph nodes.
The granulomas likely result from an immuneresponse to the tumor.
