Area of Science:

Gastroenterology
Pathology
Surgical Oncology

Background:

A 40-year-old male presented with a 3-year history of intermittent upper abdominal pain.
Diagnostic imaging revealed a gastric tumor originating from the serosa, initially suspected to be a gastrointestinal stromal tumor.

Observation:

Gastroscopy and endoscopic ultrasonography showed a homogenous, low echogenicity tumor.
Contrast-enhanced computed tomography (CT) scan demonstrated a well-marginated, ovoid mass with specific enhancement patterns.

Findings:

Postoperative pathological examination unexpectedly revealed normal splenic tissue, not a tumor.
This represents the first documented instance of ectopic splenic tissue originating from the gastric serosa.

Implications:

Highlights the importance of considering rare differential diagnoses in gastric masses.
Crucial for accurate identification and management of gastric tumors, preventing misdiagnosis and unnecessary treatment.
Contributes to understanding rare congenital anomalies and their clinical presentation.
