Show Hint
Which viral esophagitis gives winding serpentine ulcers in the lower esophagus that can merge into giant ulcers?
Updated On: Jun 23, 2026
- CMV
- Herpes
- Pill
- Corrosive
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: The shape and site of an esophageal ulcer are strong clues to its cause in infectious esophagitis.
Step 2: A winding, serpentine ulcer sitting low in the esophagus, sometimes merging into a giant ulcer, is the signature of cytomegalovirus.
Step 3: Herpes gives small punched-out shallow ulcers, a lodged tablet gives a focal pill-induced ulcer, and a corrosive agent burns the lining diffusely, so none of these matches a serpiginous distal pattern.
Step 4: The lesion described therefore points to CMV.
\[\boxed{\text{CMV}}\]
