A barium swallow (Fig. 1A) revealed marked narrowing at the distal esophagus. A gastroscopy was performed which confirmed the presence of a distal esophageal stricture. Within the granulation tissue, isolated foci of larger, atypical cells displaying nucleomegaly were identified (Fig. 1B). CMV immunohistochemistry. CMV immunohistochemical stains highlighted the presence of multiple foci of cells showing strong, nuclear staining, confirming the presence of CMV infection (Fig. 1C).
