Gastric duplication cyst with hemoptysis: an unusual presentation.

Gastrointestinal duplications are rare developmental anomalies that may occur at any level from the oral cavity to the rectum, with the ileum being the most common site. Gastric duplications are rare gastrointestinal duplications. Various theories have been proposed for the development of duplication cysts; however, there is no single theory that explains all types of duplications. Complete removal is the treatment of choice to avoid the risk of possible complications and malignant transformation. Most cases present within the first year of life. The clinical presentation of gastric duplications can be highly variable; however, they usually present with abdominal pain and a lump. Clinical presentation with hemoptysis is rare. Only one such case has been reported previously. We describe a three-year-old male with gastric duplication who presented with hemoptysis.
