Stomach, Cardia Lesion, Biopsy:
- Polypoid gastric xanthoma.
- NEGATIVE for Helicobacter-like organisms.
- NEGATIVE for intestinal metaplasia.
- NEGATIVE for dysplasia and NEGATIVE for malignancy.
Comment:
The histiocytes in were demonstrated with a CD68 immunostain.
An AE1/AE3 immunostain and a Ki-67 immunostain have a benign pattern.
