Esophageal Duplication Cyst Masquerading as a Stromal Tumor in an Adult

The incidence of gastrointestinal tract duplication cysts is 1:100,000, with only about 160 cases described in adults. They are rare anomalies, 25% of which occur in the esophagus [1]. They most commonly present in infancy and in childhood. In adults they may cause symptoms due to mass effect. When symptomatic, surgical excision is usually recommended as risk of complications, such as intracystic hemorrhage, cyst rupture, infection and very rarely malignant transformation, increase [2].
