Abstract

Esophageal carcinoid tumors remain some of the rarest of all carcinoid tumors, with only several cases previously reported in the literature. The endoscopic mucosal resection of selected carcinoid tumors has been shown to be a valid, safe, and effective method of treatment. Endoscopic ultrasonography is the technique of choice to select patients eligible for endoscopic resection. Here, we report successful endoscopic mucosal resection of a low esophageal carcinoid tumor and review the relevant literature. The present case is the first reported case of esophageal carcinoid tumor in Korea.

• 

  Fig. 1 Endoscopic view of the lesion. An 0.8×0.5-cm, ovoid, elevated, submucosal esophageal lesion was noted 35 cm from the upper incisors.

• 

  Fig. 2 Endoscopic ultrasound image of the lesion. Endoscopic ultrasonography shows homogenous, hypoechoic lesion within the mucosal layer.

• 

  Fig. 3 The specimen after endoscopic mucosal resection.

• 

  Fig. 4 Histologic examination of the resected specimen. The tumor was located in the mucosal layer, and overlying normal squamous epithelium was seen. The tumor consisted of round cells arranged in sheets (H&E stain, ×100).

• 

  Fig. 5 Immunohistochemical of examination the resected specimen (×200). The tumor cells show positive reaction for synaptophysin.
