Gastric high-grade dysplasia is an important premalignant lesion in gastric epithelial cells and has a high possibility of transforming to adenocarcinoma. Therefore, biopsy-proven high-grade dysplasia should be treated with en bloc resection methods such as endoscopic mucosal resection or endoscopic submucosal dissection (ESD). We report the case of a 63-year-old male patient, diagnosed with gastric high-grade dysplasia at the angle and lesser curvature side of the lower body. The patient was initially treated with ESD, although histopathology subsequently showed horizontal margin involvement. Since the lesion was diffusely edematous and margins were uncertain because of the previous ESD treatment, we chose to treat the patient with laparoscopy-assisted endoscopic full-thickness resection (EFTR). EFTR is a recently developed procedure, which uses both endoscopic and laparoscopic techniques to resect the full-thickness of the tissue. The final pathologic report revealed high-grade dysplasia and a focal intramucosal carcinoma of 0.8×0.7 cm. We conclude that EFTR can be an effective alternative treatment in gastric high-grade dysplasia unsuitable for ESD.

The incidence of early gastric cancer (EGC) has increased to >50% in Korea owing to a higher detection rate caused by rapid advances in diagnostic instrumentation. EGC with distant metastasis has been rarely reported. Here, we report the case of a 76-year-old woman in whom general EGC was initially diagnosed by endoscopy and endoscopic ultrasonography. She subsequently underwent endoscopic submucosal dissection (ESD). Histological examination of the ESD specimen revealed that neoplastic cells were located predominantly in the submucosal layer and submucosal lymphatic channels. Metastatic cancer cells were also found in the pleural effusion. After conducting all analyses, including immunohistochemical staining, we concluded that the patient had primary EGC with pleural metastasis.

Solitary pancreatic metastasis of esophageal cancer is extremely rare. We report the case of a 58-year-old male admitted with esophageal cancer. Additional asymptomatic solitary hepatic and pancreatic masses were observed in the staging work-up for esophageal cancer. The hepatic mass was confirmed as a primary hepatocellular carcinoma with an ultrasound-guided needle biopsy. An esophagectomy with a distal pancreatectomy and radiofrequency ablation for hepatocellular carcinoma were performed. Histologically, the pancreatic mass was confirmed to be a metastasis from the esophageal cancer. The patient has been followed up with chemotherapy.
