Primary Small Bowel GIST Presenting as a Life-Threatening Emergency: A Report of Two Cases

Abstract EN

Gastrointestinal stromal tumor (GIST) is a rare stromal neoplasm, which represents the most common mesenchymal tumor of the gastrointestinal tract.

It is characterized by indolent clinical symptoms, although it can present as a life-threatening emergency.

Herein, we present two cases of primary small bowel GIST treated at our department.

A 68-year-old female patient presented to our emergency department with a diffuse abdominal pain of acute onset.

Imaging studies revealed a mass at proximal jejunum, with a nearby free air and fluid.

At surgery, a mass of 9 cm was found at proximal jejunum, 3 cm distal to the treitz ligament, with perforation on the lateral wall of the mass.

En bloc resection was performed.

Pathology report was positive for gastrointestinal stromal tumor.

A 70-year-old male patient presented to our emergency department with 3 days of dark tarry stool and few hours of hematochezia.

Computed tomography angiography revealed a mass at the pelvis, with calcifications, attached to the distal ileum, with intraluminal blush of intravenous iodine.

At surgery, a mass of 8 cm at the distal ileum was found.

Resection of the mass along with a 20 cm of ileum was completed.

Histopathology report was positive for malignant gastrointestinal stromal tumor.
