Extra luminal colonic gastrointestinal stromal tumor: a case report.

Area of Science:

• Gastroenterology
• Surgical Oncology
• Pathology

Background:

• Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract, typically arising in the stomach or small intestine.
• GISTs originate from the interstitial cells of Cajal and can present with varied symptoms including pain, bleeding, or obstruction, though small tumors may be asymptomatic.
• Colonic, rectal, and esophageal GISTs are rare occurrences.

Observation:

• A case report of a 34-year-old female presenting with a 4-month history of a slowly growing epigastric mass and discomfort.
• Imaging revealed a large extra-colonic mass adjacent to the transverse colon, without signs of luminal obstruction.
• Histological examination confirmed the mass as a gastrointestinal stromal tumor.

Findings:

• Extra-luminal colonic gastrointestinal stromal tumors are exceptionally rare.
• These tumors can manifest clinically as a palpable abdominal mass.
• Surgical resection is the definitive treatment for GISTs.

Implications:

• This case underscores the importance of considering GIST in the differential diagnosis of abdominal masses, even in rare locations like the colon.
• Early diagnosis and surgical intervention are crucial for favorable outcomes in patients with gastrointestinal stromal tumors.
• Further research into the etiology and management of rare GIST presentations is warranted.
