Rare presentation of post-transplant lymphoproliferative disorder isolated to gastroesophageal junction

Figure 1 Esophageal ulcers (arrows) noted on upper endoscopy on initial presentation (A), and repeat endoscopy 10 d later shows significantly enlarged ulcers (arrows) (B).

Figure 2 Biopsy results. A: Esophageal biopsy, with circled area showing a large endothelial cell with cytomegalovirus inclusions; B: Positive CD20 staining; C: Epstein Barr virus encoded RNA in situ hybridization showing positive staining; D: Positive Ki-67 staining in most of the lymphoma cells.

Figure 3 Above shows a coronal section of positron emission tomography-computed tomography showing increased uptake at the gastroesophageal junction. Green arrow points to the area of increased activity.
