Barrett esophagus vs Esophageal adenocarcinoma
How to tell Barrett esophagus and Esophageal adenocarcinoma apart when a board question makes them look alike.
Barrett esophagus: premalignant intestinal metaplasia with goblet cells; adenocarcinoma: invasive gland-forming cancer through the basement membrane.
Side by side
Premalignant intestinal metaplasia in distal esophagus after chronic GERD, with columnar epithelium and goblet cells.
Invasive gland-forming malignancy, often distal esophagus, with progressive dysphagia, weight loss, or mass after Barrett risk.
Chronic acid injury drives squamous-to-columnar intestinal metaplasia as an adaptive but premalignant change.
Dysplastic metaplastic epithelium can progress to invasive malignant glandular growth.
Goblet cells in distal esophageal biopsy support Barrett esophagus.
Invasion, malignant glands, mass lesion, progressive dysphagia, and weight loss support adenocarcinoma.
The trap
Barrett esophagus on biopsy does NOT mean adenocarcinoma. Barrett is premalignant metaplasia, not invasive cancer. The progression sequence is chronic GERD to Barrett (intestinal metaplasia with goblet cells) to low-grade dysplasia to high-grade dysplasia to adenocarcinoma. Management changes at each stage: PPI for GERD, surveillance endoscopy for Barrett (every 3 to 5 years without dysplasia, more often with dysplasia), endoscopic eradication (radiofrequency ablation or endoscopic mucosal resection) for dysplasia, and esophagectomy plus chemoradiation for invasive adenocarcinoma. Squamous cell carcinoma of the esophagus (upper and middle esophagus, smoking and alcohol risk factors) is a separate disease that does NOT arise from Barrett.
The repair move
For Barrett questions, decide whether the biopsy shows premalignant metaplasia or invasive glandular cancer.
Try a free question
CoreA patient with long-standing GERD has biopsy from the distal esophagus showing nonkeratinized columnar epithelium with goblet cells. Which diagnosis is most likely?
Show answer and explanation
Answer: A. Barrett esophagus. Barrett esophagus is intestinal metaplasia with goblet cells in the distal esophagus after chronic reflux injury.
Why the other choices are tempting
- B. Adenocarcinoma is invasive malignant gland-forming tumor, often arising from Barrett.
- C. Squamous carcinoma arises from squamous epithelium and is more often mid/upper esophagus.
- D. Achalasia is a motility disorder.
- E. Candida esophagitis has plaques and yeast/pseudohyphae.
