Abstract

A small subepithelial esophageal lesion was seen 21 cm from the incisors in an otherwise unremarkable examination. Subsequent upper-EUS examination revealed a 14 mm by 21 mm well-circumscribed, hypoechoic lesion originating from the muscularis propria (layer 4). The initial EUS impression was suggestive of a GI stromal tumor, however, examination of EUS-guided fine-needle biopsy specimens showed a haphazard arrangement of spindle cells in a fibrotic stoma.
