Gastric Glomus Tumor (GGT) Mimicking Gastrointestinal Stromal Tumor (GIST): A Case Report and Literature Review

Gastric glomus tumor (GGT), a rare mesenchymal neoplasm, has only been reported in a few cases, and there are no established guidelines for its management. Diagnosing a gastric glomus tumor preoperatively is challenging due to its location and lack of specific clinical and endoscopic characteristics. Confirmation through biopsies before surgical resection is rare. Although most cases are benign, some may exhibit malignant features. Treatment typically involves wide local excision, with long-term follow-up necessary due to the potential for malignancy. Here, we present the case of a 41-year-old female who was diagnosed with a GGT postoperatively using histopathology and immunohistochemistry.
