Figure

• 

  Fig. 1. Endoscopic findings. (A) Endoscopic appearance of a single polypoid lesion without any visible mucosal changes. (B) Appearance of air bubble during submucosal dissection (arrow).

• 

  Fig. 2. Morphologic findings of the lesion. (A) Submucosal inflammatory fibroid polyp and a number of clear vacuoles overlying within the mucosa, mimicking lymphangioma or lipomatous metaplasia. (B) High resolution view of the lesion. The characteristic appearance of pseudolipomatosis shows a number of unlined empty spaces with various sizes in an otherwise intact mucosa. (C) Negative immunoreactivity for D2-40 on vacuoles. D2-40 immunostaining highlighted the preexisting lymphatic structures (arrow). (D) Presence of incompletely removed air inside the syringe (arrow).
