Metastatic tumors to the liver resulting in fulminant hepatic failure are a rare occurrence and have not been previously described in patients with gastrointestinal stromal tumor (GIST). A 70 year-old man was referred to hospital with postprandial discomfort. On examination a 19.5 cm large epithelioid GIST of the stomach was diagnosed. The mass exhibited unfavorable prognostic features: mitotic index 18/50 high-power fields, large primary tumor size and male sex. Complete tumor resection with negative margins was achieved and metastases were not detected. The patient presented six months later with jaundice, asterixis and elevated liver enzymes. Computerized tomography showed multiple liver hypodense lesions representing metastases. Treatment with imatinib mesylate was of no avail and the patient died 3 days later as the result of hepatic failure. Massive liver metastases can, even though rarely, be responsible for fulminant hepatic failure. Clinical and radiological follow-up are crucial in patients with GIST even after surgical resection.

I have had nothing but positive experiences publishing with Libertas Academica. The publication procedure is as quick and smooth as any I've encountered, and the peer review process is sufficiently rigorous that the reader can have complete confidence in the content of its journals.
All authors are surveyed after their articles are published. Authors are asked to rate their experience in a variety of areas, and their responses help us to monitor our performance. Presented here are their responses in some key areas. No 'poor' or 'very poor' responses were received; these are represented in the 'other' category.See Our Results
