Conclusion
The finding of cobblestone esophagus should prompt physician to
investigate for an underlying etiology. In addition to performing
endoscopy and biopsies to exclude common etiologies, this case shows us
the importance of taking a comprehensive drug history. Patients with
drug induced esophagitis may be asymptomatic initially. It is an easily
reversible etiology that should be routinely considered for prompt
intervention against irreversible damage to the upper gastrointestinal
tract.
