A LIVING LIBRARY OF COMMON AND RARE ENDOSCOPIC FINDINGS

Esophageal leiomyoma

Location: Mid esophagus.

Optical impression: Smooth, hemispheric subepithelial bulge with intact, featureless overlying mucosa on NBI and well-circumscribed borders—suspicious of leiomyoma (vs GIST).
(In this case leiomyoma EUS-verified).

Plan: EUS to confirm layer of origin (muscularis propria) and size; observe if asymptomatic and <2 cm, resect if symptomatic, enlarging, or >2 cm.
