Huge Lymphangioma of the Esophagus Resected by Endoscopic Piecemeal Mucosal Resection

Figure 1

(a) Endoscopic finding. A large, whitish-yellow, translucent mass with a lustrous surface in the mid and distal esophagus, located 32 to 38 cm from the incisors. (b) Endoscopic ultrasound finding. A honeycomb-like hypoechoic structure measuring 60 × 10 mm located in the submucosa with heterogenous echo pattern; the muscularis propria was intact. (c)-(d) Abdominal CT. Contrast-enhanced CT showed the lesion located in the lower esophagus. (e)–(h) The esophageal mass was resected by endoscopic piecemeal mucosal resection (EPMR). (i) Histology of the resected mass showing cystically dilated lymphatics in the surface squamous epithelium and in the submucosa. (hematoxylin and eosin [H&E], magnification ×200).
