Case #236 – September, 2008

A 30-year-old who frequents sushi restaurants started experiencing severe gastritis, including epigastric pain, nausea and vomiting. He had reported eating at a sushi restaurant the previous day. After being admitted to the hospital for severe pain, a gastric biopsy was performed. A tissue specimen was sectioned and stained with hematoxylin and eosin (H&E). The attending pathologist observed unusual structures from the biopsied material and sent the slide to the CDC for diagnostic assistance. Figures AC show structures observed on the slide; images were captured at 100x, 200x and 400x, respectively. What is your diagnosis? Based on what criteria?
