Complete excision of the tumour with adjuvant therapy is a curative option. The patient presents with non-specific upper gastrointestinal symptoms. Preoperative biopsy and immunostaining with endoscopic ultrasound guidance is the most accurate tool for diagnosis. We present here a case of a middle-aged man, presenting with upper abdominal heaviness and a lump which progressed rapidly in size over a few weeks, associated with appetite and weight loss. Radiographic evaluation was suggestive of a large tumour of the left lobe of the liver, possibly hepatocellular carcinoma, due to raised protein induced by vitamin K absence-II levels. Intraoperatively, it turned out to be of gastric origin, in relation to the liver.\u2003<\/jats:p>","DOI":"10.1136\/bcr-2025-265246","type":"journal-article","created":{"date-parts":[[2025,9,25]],"date-time":"2025-09-25T10:30:20Z","timestamp":1758796220000},"page":"e265246","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Gastric
