What is the Pathology of Mucosal Atrophy?

The pathology of mucosal atrophy is:

-Etiology: The causes of mucosal atrophy are autoimmune due to pernicious anemia or chronic Helicobacter pylori infection.

-Genes involved: None.

-Pathogenesis: The sequence of events that lead to mucosal atrophy are low gastric acid output and hypergastrinemia, which may lead to enterochromaffin-like ECL cell hyperplasia and carcinoid tumors.

-Histology: The histology associated with mucosal atrophy shows severe mucosal damage, erosions and hemorrhage.

How does Mucosal Atrophy Present?

Patients with mucosal atrophy typically more severe in men and present at any age range. The symptoms, features, and clinical findings associated with mucosal atrophy include: stomach pain, nausea and vomiting, loss of appetite, unexpected weight loss, stomach ulcers.

How is Mucosal Atrophy Diagnosed?
