RESUMO
Common extrahepatic metastasis sites of hepatocellular carcinoma (HCC) are the lungs, adrenal glands, and bones. Herein, we report a rare case of metastatic gastric, pancreatic, and renal tumors from HCC simultaneously, and review the relevant literature. A 75-year-old woman presented with right hypochondralgia, appetite loss, and weight loss. Computed tomography revealed suspected metastatic liver, lung, and renal tumors. A blood test revealed a leukocyte count of 26,210/µL and a high inflammatory reaction. As sepsis was suspected, the patient was referred to our hospital. Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging revealed a hypovascular liver tumor that was suspected to be metastatic. Upper gastrointestinal endoscopy revealed two suspected metastatic gastric tumors. Liver and gastric tumor biopsies revealed poor carcinoma in both. The patient's condition gradually worsened and she died on day 8 of the illness. Based on autopsy findings, the patient was finally diagnosed with metastatic gastric and renal tumors originating from HCC. Additionally, a metastatic pancreatic tumor originating from the HCC was identified during autopsy. The pathological diagnosis of the pulmonary lesion was primary lung adenocarcinoma. In conclusion, HCC should be suspected in cases with multiple metastases of unknown primary lesions.
