Lymphocytic infiltrate stomach

Lymphoid hyperplasia of the stomach is characterized by distinctive findings on double-contrast upper gastrointestinal tract barium examinations; all five patients had innumerable tiny (1-3 mm in diameter) round frequently umbilicated nodules that carpeted the mucosa of the gastric antrum or antrum and body Lymphocytic infiltration of the pituitary is a rare disorder, which most commonly occurs in postpartum women.50 Common presentations are headache with inability to lactate postpartum due to impaired prolactin production or polyuria and polydipsia from diabetes insipidus.51 Some women are relatively asymptomatic but develop amenorrhea or non-specific symptoms of hypopituitarism over time In the stomach, it is particularly important to exclude Helicobacter pylori infection and celiac sprue before diagnosing lymphocytic gastritis. Duodenal lymphocytic infiltrates, inextricably tied with alterations of the villous architecture of the mucosa, are often caused by gluten sensitivity

Various gastrointestinal infiltrations have been described in patients with chronic lymphocytic leukaemia (CLL). Here, we report a 69-year-old man with CLL and anaemia in whom the macroscopic finding of colonoscopy was normal, but the histological specimens revealed lymphocytic leukemia in ileum and in colon The cause of Jessner lymphocytic infiltrate is unknown. It is classified as a benign T-cell lymphoproliferative disorder. Some cases have been associated with Borrelia infection, the cause of Lyme disease Inflammation can be caused by acid from the stomach or by infection. The most common cause of infection is the bacteria Helicobacter pylori (also known as just H. pylori). When the stomach gets infected with this bacteria, it can cause problems like gastritis (irritation of the stomach) and stomach ulcers Gross leukemic lesions are most common in the stomach, ileum, and proximal colon 1, 5 and include nodules, plaques, diffuse infiltrates, polyps, and a convoluted brain-like appearance of the mucosal folds. 1 Leukemia can affect different and multiple anatomical sites of the GI tract. 6 In almost 3% of cases, extensive segments of the GI tract are involved. 1 Because leukemic plaques involve the submucosa or muscle coats, they may be associated with ulcerations and intestinal perforation medullary carcinoma with lymphocytic infiltration of the stomach by an immunohistochemical analysis of the subpopulations of tumor-infiltrating lymphocytes. This carcinoma was histologically characterized by the sparse population of small nests consisting of poorly differentiated carcinoma cells, widel

The lymphoid infiltrate in this case is displacing the crypts. The infiltrate consists of monomorphous small lymphocytes, without evidence of germinal center formation. Some histologic features can help to distinguish reactive lymphoid aggregates from lymphoma (Table 1, Figure 2) Lymphocytic esophagitis is a rare and poorly understood medical disorder involving inflammation in the esophagus. The disease is named from the primary inflammatory process, wherein lymphocytes are seen within the esophageal mucosa. Symptoms of the condition include difficulty swallowing, heartburn and food bolus obstruction Infiltration of lymphocytes in the lamina propria is unspecific and can be observed in all segments of the gastrointestinal tract.

Abstract Corpus-dominant lymphocytic gastritis (LyG) is characterized by CD8+ T-cell infiltration of the stomach epithelium by a so far uncharacterized mechanism. Although Helicobacter pylori is typically undetectable in LyG, patients respond to H. pylori antibiotic eradication therapy, suggesting a non-H. pylori microbial trigger for the disease

Moderate grades of lymphoplasmacytic infiltration were common in organs such as salivary glands, esophagus, stomach, urinary bladder, lungs, and kidneys. They were often associated with lymphoid nodules or follicles around salivary gland ducts, small arteries in the urinary bladder, and bronchi and blood vessels in the lungs Intraepithelial lymphocytes in small bowel and stomach were positive for the antibody MT-1, indicating a T-cell infiltrate at both sites. These findings suggest that lymphocytic gastritis may occur as a manifestation of celiac sprue or spruelike disease and that the lymphocytic infiltration of celiac sprue may affect gastric epithelial mucous.

Lymphocytic gastritis has been linked to coeliac disease and Helicobacter pylori infection. AIMS: To determine whether H pylori eradication leads to resolution of the lymphocytic infiltrate and clinical improvement in patients with lymphocytic gastritis, and to determine their HLA status The infiltration of the intestine by certain inflammatory cells (lymphocytes and plasma cells) leads to an inflammatory bowel condition and enlargement of the lymphatic tissue associated with the intestine. The infiltration can lead to various degrees of villous blunting or atrophy, mucosal and submucosal oedema, necrosis, and mucosal haemorrhages Gastric biopsies demonstrated a dense infiltrate of lymphocytes in the lamina propria consistent with lymphocytic gastritis. The histology showed no evidence of H. pylori or lymphoma. The patient's antiendomysial and antigliadin antibodies were negative, but she had a low-normal quantitative IgA level and she was HLA-DQ8 positive
