Figure 1 A 30-year-old white man with familial adenomatous polyposis (FAP) was referred for
evaluation of Barrett’s esophagus with high-grade dysplasia, an association not previously
reported. Diagnosed during adolescence with FAP, he had undergone proctocolectomy
in 1996. Subsequently, screening endoscopy for duodenal polyps detected long-segment
Barrett’s glandular mucosa replacing most of the esophageal mucosa (14 cm segment
length), with polypoid changes. Similar-appearing polyps were noted throughout the
stomach and duodenum.
Figure 2 The histopathology section demonstrates overlying normal esophageal squamous mucosa,
undermined by Barrett’s glandular epithelium with high-grade dysplasia. The patient
declined invasive treatment with porfimer sodium photodynamic therapy or esophageal
resection. Medical therapy with a nonselective nonsteroidal anti-inflammatory drug,
combined with high-dose proton-pump inhibitor treatment, was initiated.
