Abstract
Introduction: Gastric duplication cysts are a rare congenital disease, diagnosed mainly in the neonatal stage, being rare in adulthood. Most of these lesions are unique, non-communicating, usually asymptomatic and difficult to diagnose preoperatively, with definitive diagnosis being common during intraoperative and with histological study of the piece.
Clinical case: A 70-year-old male patient with a symptomatic lesion was presented in which the complete resection of the lesion was performed.
Discussion: The correct preoperative diagnosis of this entity is difficult despite the use of advanced imaging techniques, being confused with other pathological entities. The importance of a correct diagnosis lies in the fact that although malignant transformation is very rare, it has been reported in the literature.
Conclusion: The gastric duplication cyst must be taken into account in the differential diagnoses of any cystic tumour of the gastrointestinal tract. They are potentially malignant lesions, and complete resection provides the definitive diagnosis.
