Erosion vs.

Ulceration?

This question can be very confusing for medical students and residents. Hopefully this post will help clear it up for you. Have a read!

Infectious

Organisms

Biopsies of the esophagus are submitted in any case of esophageal ulceration seen on endoscopy. Common infectious causes include candida (fungal), HSV and CMV viral infections. Continue reading to learn the high yield findings to diagnose each infection.

Candida

HSV

CMV

 

Helicobacter Infections

(H. pylori or H. Heilmannii)

While you will encounter this much more commonly in gastric or duodenal biopsies, H. pylori infections can still present in biopsies taken of the esophagus. Continue reading to learn tips & tricks to identifying this nasty little bug

GastroEsophageal

Reflux Disease (GERD)

Patients often present with "acid reflux" and pathologists are asked to assess for GERD. Continue reading to find out the key features for making this diagnosis.

 

In the setting of chronic insult to the esophagus (such as GERD), the epithelium will go through a series of histologic changes including intestinal metaplasia (Barrett esophagus), dysplasia and can eventually lead to carcinoma. Read the full post below for more details on how to identify these key entities...

Barrett Esophagus

(Intestinal Metaplasia)

 

With the wide use of so many medications in today's society, it is not uncommon to see injury due to impacted pills in the esophagus. Common medications known to cause esophageal ulcers include iron, kayexalate, sevelamer, bile acid sequestrants (Cholestyramine) and bisphosphonates. Continue reading to see more high yield findings that are key to making the correct diagnosis.
