Asymptomatic adenocarcinoma arising from a gastric duplication cyst: A case report

Abstract

From our long-term follow-up experience of this gastric duplication cyst, we recommend making accurate diagnosis as soon as possible with biopsy using endoscopic ultrasonography. When the disease is diagnosed as malignant, we recommend gastrectomy with lymphadenectomy. Even if the disease is diagnosed as benign, we recommend close observation with imaging modalities.
