A 69-year-old man with fever and sudden epigastralgia was found in abdominal computed tomography to have a mass 11 cm in diameter near the greater curvature having a heterogeneous pattern with intermediate contrast. Abdominal angiography showed tumor staining from the right gastoepiploic artery. Surgery was conducted for a suspected mesenchymal tumor arising from the greater curvature. The tumor was found localized in the greater omentum and resected. Histological examination showed the tumor consisted of spindle-shaped cells. Immunohistochemical testing was positive for CD34 and C-KIT, identifying the tumor as a primary gastrointestinal stromal tumor of the greater omentum.
