A rare cause of gastrointestinal bleeding, "GANT"

Area of Science:

• Gastroenterology
• Surgical Pathology
• Oncology

Background:

• Acute gastrointestinal hemorrhage is a common surgical emergency.
• Benign pathologies typically cause acute gastrointestinal bleeding.
• Gastrointestinal tumors, though rare, must be considered in the differential diagnosis.

Observation:

• This case report details a patient presenting with acute gastrointestinal hemorrhage.
• The patient was diagnosed with a gastrointestinal autonomic nerve tumor (GANT).
• GANTs are rare mesenchymal tumors originating from Cajal cells or their precursors.

Findings:

• Gastrointestinal autonomic nerve tumors (GANTs) are exceptionally rare.
• Cajal cells function as pacemaker cells within the intestinal wall.
• This case underscores the potential for GANTs to manifest as acute gastrointestinal bleeding.

Implications:

• Reporting rare GANT cases contributes to understanding the etiology of acute gastrointestinal hemorrhage.
• Such cases may offer new perspectives on the diagnosis and management of rare gastrointestinal tumors.
• Further research into rare mesenchymal tumors is warranted to improve diagnostic and therapeutic strategies.
