IHC
- CD68 +ve.
- Panker (AE1/AE3) -ve.
- To exclude carcinoma.
Sign out
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.
