Gastritis-I: Introduction and Types01:27

Gastritis-I: Introduction and Types

689
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

443
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

1.9K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Gastritis III: Clinical Manifestations and Management

388
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

Detailed Structure and Function of Lymph Nodes01:23

Detailed Structure and Function of Lymph Nodes

2.1K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

Hormones Secreted by the Stomach01:25

Hormones Secreted by the Stomach

777
Enteroendocrine cells, accounting for only 1% of stomach epithelial cells, play a significant role in digestion and are classified by their digestive hormone secretions.
Each of these hormones secreted by different enteroendocrine cells plays a unique role in digestion. Here are a few examples:

Area of Science:

  • Endocrinology
  • Oncology
  • Surgical Pathology

Background:

  • Gastrinomas, neuroendocrine tumors, are typically found in the duodenum and pancreas.
  • They are often associated with Multiple Endocrine Neoplasia and Zollinger-Ellison syndrome.
  • Lymph node gastrinoma is an exceptionally rare presentation.

Observation:

  • A 64-year-old male presented with symptoms indicative of a gastrinoma.
  • Diagnostic evaluation revealed an unusual lymph node tumor.
  • The tumor was surgically removed.

Findings:

  • The patient was diagnosed with a lymph node gastrinoma.
  • Surgical resection of the lymph node gastrinoma was performed.
  • Immediate and complete remission of symptoms was achieved post-surgery.

Implications:

  • This case highlights the importance of considering rare tumor locations for accurate diagnosis.
  • Successful surgical management of lymph node gastrinoma can lead to excellent patient outcomes.
  • Further research into the etiology and optimal treatment of extranodal gastrinomas is warranted.
