Summary
This case report details a gastric stromal tumor diagnosed in a 54-year-old woman. Surgical resection and histological analysis confirmed the diagnosis, highlighting extramural growth.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Gastric stromal tumors are common mesenchymal neoplasms of the upper gastrointestinal tract.
- Submucosal mass lesions in the stomach require thorough evaluation for accurate diagnosis and treatment planning.
Observation:
- A 54-year-old woman presented with an incidentally discovered mass between the stomach and pancreas.
- Imaging studies including ultrasonography, CT, and endoscopic ultrasonography localized a hypervascular mass near the stomach's lesser curvature.
- Left gastric arterial angiography suggested a hypervascular nature, leading to a preoperative diagnosis of leiomyosarcoma.
Findings:
- Laparotomy revealed a 5 cm solid mass along the stomach's minor curvature.
- Histopathological examination confirmed a gastric stromal tumor with CD34 immunoreactivity.
- The tumor exhibited extramural growth, a less common presentation.
Implications:
- This case underscores the importance of comprehensive imaging and diagnostic workup for gastric stromal tumors.
- Understanding extramural growth patterns is crucial for surgical planning and patient management.
- CD34 immunoreactivity is a key diagnostic marker for gastric stromal tumors.
