Gastrointestinal pathology

Where unusual is usual

In our practice, we review both luminal GI tract specimens and solid viscera. We cover the spectrum of pathology from routine to highly esoteric. We interpret more than 25,000 in-house biopsies annually and more than 10,000 consultation cases each year.
