Abstract

We report a case of a 13-yr-old white boy with juvenile onset pernicious anemia in association with IgG deficiency. He had marked gastric atrophy, intestinal metaplasia of the stomach, and an intractable antral ulcer that required surgery. In addition, his gastric mucosa showed evidence of a progressive squamous metaplasia. Diffuse squamous metaplasia of the stomach, a very rare gastric lesion, has not previously been described either in association with pernicious anemia, atrophic gastritis, or hypogammaglobulinemia. This patient also has ulcerative colitis involving the entire colon and partial villous atrophy noted on small intestinal biopsy.

Atrophic Gastritis

Atrophic Gastritis is a process where gastric glandular cells are lost and replaced with firbous tissues, as a result of chronic inflammation. Learn more about Atrophic Gastritis here.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
