This case report describes a patient with esophageal retention cyst. A 77-year-old man was admitted to our hospital on December 15th, 1985 for further evaluation of a protruded lesion of the esophagus. On gastrointestinal roentgenogram, a smooth surfaced semi-pedunclated protruded lesion was recognized in the lower esophagus (Figure 1). Endoscopical examination of the esophagus showed a smooth surfaced, semi-pedunclated submucosal tumor at 39 cm from the incisors. The tumor was soft and 1.6 cm in diameter (Figure 2). The endoscopical diagnosis was a cystic lesion such as cyst or lymphangioma. Polypectomy was performed and the submucosal lesion was removed completely. The specimen measured 1.5×1.6×1.0 cm and was a cystic lesion filled with clear fluid (Figure 3, 4). Histological diagnosis of the specimen was a retention cyst of the esophagus (Figure 5, 6). Only 3 cases of esophageal retention cyst including our case have been reported so far in Japan (Table 1).
