A. Duodenum, Biopsy: | |||
- Abundant micro-organisms consistent with GIARDIA and small | |||
bowel mucosa with increased intraepithelial lymphocytes, see comment. | |||
- NEGATIVE for dysplasia. | |||
B. Stomach, Biopsy: | |||
- Body and antral-type mucosa with mild chronic inactive inflammation. | |||
- NEGATIVE for Helicobacter-like organisms. | |||
- NEGATIVE for intestinal metaplasia. | |||
- NEGATIVE for dysplasia and NEGATIVE for malignancy. | |||
Comment: | |||
The increased intraepithelial lymphocytes are likely to due to the Giardia; however, other | |||
causes cannot be excluded. | |||
