Abstract
Glomus tumors are rare neoplasms originating from smooth muscle cells of the glomus body. They rarely involve the gastrointestinal tract, and when they do, they present as acute gastrointestinal bleeds with symptoms such as hematemesis or melena. We present a rare case of a gastric glomus tumor in a 50- year- old male presenting with shortness of breath and gastrointestinal bleed requiring transfusions. Coincidently, he was also found to have a pulmonary embolism that usually would require anticoagulation, which was contraindicated in an active gastrointestinal bleed. He eventually required an inferior vena cava (IVC) filter and underwent a partial gastrectomy. Due to gastric glomus tumor being a rare entity, there is a paucity of data to have a classification and grading or staging system, and tumors are usually considered benign. The exact diagnosis is dependent on histopathological findings as it can mimic a gastrointestinal stromal tumor (GIST). Pulmonary embolism, a common phenomenon, can often be seen in patients with malignancy. Our patient was diagnosed with a glomus tumor which is usually benign. As per our literature search, there are no documented cases of GGT with concomitant Pulmonary embolism diagnosis that would point to a causal association.
