Locally Advanced Glomus Tumor of the Stomach With Synchronous Liver Metastases: Case Report and Literature Review

Gastric glomus tumors (GGTs) are usually rare mesenchymal neoplasms. They are typically benign, with very few metastatic cases reported and no specific guidelines on their management. Here, we present a patient with a locally advanced GGT with synchronous liver metastases. One month after resection of the GGT, emergency laparotomy was required for massive hemoperitoneum due to bleeding from the largest metastasis. Indeed, a dramatic progression of liver metastases was observed in just one month. A wide local excision is considered the treatment of choice for GGTs. In particular, this case report suggests that the resection of any liver metastases should possibly be performed at the same time as the GGT excision and not at a later stage.
