Co-occurrence of liver metastasis of gastrointestinal stromal tumor and hepatocellular carcinoma: a case report.

摘要: Gastrointestinal stromal tumors (GISTs) are potentially malignant mesenchymal that can give rise to distant metastases, mainly in the liver. The co-occurrence of synchronous primary liver (e.g., hepatocellular carcinoma (HCC)) patients with GIST is extremely rare. This report describes a 77-year-old male patient metastasis originating small intestine and HCC. had undergone resection for 3 years earlier partial hepatectomy radiofrequency ablation metastases 1 year earlier. Despite continuation adjuvant therapy imatinib, two new lesions were detected by follow-up computed tomography scanning, which showed gradual enlargement one tumor. A second was performed. Pathological examination revealed tumor other To our knowledge, this first
