Unusual Metastatic Malignant Gastric Glomus Tumor (Glomangiosarcoma): A Case Report and Literature Review

Abstract

Glomangiosarcoma is a pericytic neoplasm derived from glomus cells. It is a rare tumor, especially within the gastrointestinal tract. We report a female patient around 67 years old with a history of gastrectomy surgery due to a submucosal glomus tumor. After 4 years of surveillance, the patient came with thigh and hepatic metastases with the same histology (metastatic glomangiosarcoma).
