A. Polyp, Stomach, Biopsy or Polypectomy: | |||
- Polypoid fragment of gastric body type mucosa with low-grade DYSPLASIA, foveolar type, see comment. | |||
- NEGATIVE for Helicobacter-like organisms. | |||
- NEGATIVE for intestinal metaplasia. | |||
- NEGATIVE for evidence of malignancy. | |||
Comment: | |||
The sections show foveolar type epithelium with proliferation and hyperchromasia extending to the surface. A p53 and Ki-67 show diffuse staining in the abnormal epithelium. The architectural complexity is mild in the abnormal epithelium. Deepers were cut (x3); these are non-contributory. | |||
