Gastric duplication cyst with a red flag presentation: a case report.

Area of Science:

• Gastroenterology
• Surgical Pathology
• Congenital Malformations

Background:

• Gastric duplication cysts (GDC) are rare congenital gastrointestinal (GI) malformations.
• While typically benign, GDCs can present with severe complications, including massive GI bleeding.
• Accurate preoperative diagnosis is crucial for appropriate management.

Observation:

• A 28-year-old female presented with unexplained GI hemorrhage.
• Upper endoscopy revealed findings suggestive of a GI stromal tumor.
• Computed tomography (CT) scan corroborated the preoperative diagnosis.

Findings:

• Surgical resection was performed for the suspected GI stromal tumor.
• Final histopathology confirmed the lesion as a benign Gastric Duplication Cyst (GDC).
• This case underscores the diverse presentations of GDCs.

Implications:

• GDCs can mimic other GI pathologies like GI stromal tumors, necessitating thorough investigation.
• Early and accurate diagnosis of GDC is vital to prevent potentially life-threatening complications.
• Surgical management remains the definitive treatment for symptomatic GDCs.
