Summary
A gastric antrum tumor, initially appearing benign, was diagnosed as ectopic pancreas after surgery. This rare condition caused gastrointestinal bleeding in a 30-year-old man.
Area of Science:
- Gastroenterology
- Surgical Pathology
Background:
- Ectopic pancreas is a rare congenital anomaly where pancreatic tissue is found outside its normal location.
- It can occur in various gastrointestinal sites, including the stomach, duodenum, and jejunum.
- Gastric ectopic pancreas is uncommon and often asymptomatic, but can present with complications like bleeding.
Observation:
- A 30-year-old male presented with fatigue, vertigo, and melena.
- Endoscopy revealed a gastric antrum tumor with overlying mucosal bleeding, initially suspected to be benign.
- Barium meal examination also suggested a benign etiology.
Findings:
- Surgical resection (antrectomy with Billroth I anastomosis) was performed.
- Histopathological examination confirmed the tumor to be an ectopic pancreas within the gastric wall.
- The bleeding originated from the mucosa overlying the ectopic pancreatic tissue.
Implications:
- This case highlights the importance of considering ectopic pancreas in the differential diagnosis of gastric tumors, especially when presenting with bleeding.
- Accurate histopathological diagnosis is crucial for appropriate management.
- Understanding the potential complications of ectopic pancreas aids in patient care and surgical planning.
