Summary
This case study highlights a rare gastric glomus tumor. Non-exposed endoscopic wall-inversion surgery (NEWS) proved effective for complete tumor resection.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Gastric glomus tumors are rare mesenchymal neoplasms, accounting for about 1% of all gastric tumors.
- Early and accurate diagnosis is crucial for effective management.
Observation:
- A 45-year-old female presented with a 3-cm submucosal gastric antrum tumor.
- Imaging studies (CT, MRI, EUS) revealed a hypervascular, mosaic-patterned lesion.
- Immunohistochemistry confirmed a benign glomus tumor (positive for α-SMA, synaptophysin; negative for CD56, chromogranin A, C-kit; Ki-67 < 2%).
Findings:
- The patient underwent successful complete resection using non-exposed endoscopic wall-inversion surgery (NEWS).
- Histopathological examination confirmed the preoperative diagnosis of a benign gastric glomus tumor.
Implications:
- Non-exposed endoscopic wall-inversion surgery (NEWS) is presented as an effective and minimally invasive treatment option for gastric glomus tumors.
- This case contributes to the understanding of diagnostic modalities and surgical approaches for rare gastric neoplasms.
