Glomangioma of the gastric antrum: case report and literature review

Gastric glomangiomas are rare vascular tumors originating from glomic cells. We report the case of a 52-year-old woman who presented with early satiety and discomfort in the upper abdomen. Initial biopsy and imaging studies suggested a gastrointestinal stromal tumor (GIST). The tumor was surgically removed through antrectomy and lymphadenectomy, ensuring clear surgical margins. However, immunohistochemistry and histopathological examination of the removed tissue revealed that the initial diagnosis was incorrect; the patient was found to have a gastric glomangioma. This case highlights the challenges in accurately diagnosing gastric glomus tumors before surgery and reviews the prognosis and available treatment options.
