    Insights

    A rare gastric arteriovenous malformation was found incidentally during an autopsy. This unusual vascular malformation contained significant amyloid deposits, suggesting a localized form of amyloidosis.

    Area of Science:

    • Gastroenterology
    • Pathology
    • Vascular Biology

    Background:

    • Gastric arteriovenous malformations (AVMs) are rare vascular anomalies.
    • Amyloidosis involves the abnormal deposition of amyloid proteins in tissues.

    Observation:

    • An autopsy revealed a large gastric arteriovenous malformation in a 74-year-old male.
    • The AVM exhibited extensive amyloid deposits within the vessel walls.

    Findings:

    • Histochemical and electron microscopic analysis confirmed the presence and nature of amyloid.
    • This case presents an unusual association between gastric AVM and localized amyloidosis.

    Implications:

    • Highlights a rare pathological finding in the gastrointestinal tract.
    • Suggests a potential link between vascular malformations and localized amyloid deposition.
    • Warrants further investigation into the pathogenesis of such combined conditions.

    Amyloid Fibrils03:03

    Amyloid Fibrils

    Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
    Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining, normally used to...

    Esophageal Varices-I: Introduction

    Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

    Cerebral Edema ll: Pathophysiology

    Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
    Esophageal Achalasia01:27

    Esophageal Achalasia

    Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
