Abstract：Objective To investigate the diagnosis and treatment of adult rare liver tumors or tumor?like lesins. Methods The clinical data of 18 cases of rare liver tumors or tumor?like lesions were collected from June 2009 to May 2015. The clinical diagno?sis and treatment of various types of liver tumors or tumor?like lesions were analyzed retrospectively. Results In 18 cases of adult rareliver tumors or tumor?like lesions, there were 2 cases of fibrous tumor, 3 cases of adenoma,4 cases of focal nodular hyperplasia, 2 ca?ses of carcinosarcoma, 2 cases of liver hamartoma, 2 cases of inflammatory pseudotumor, 1 case of spindle cell tumor, 1 case of prima?ry malignant liver mesenchymal tumor, and 1 case of hepatic tuberculosis. Imaging misdiagnosis occurred in 8 cases, and the diagnosticaccuracy of benign and malignant lesions was 50%. CA19?9 was significantly increased(246?? 4 kU/ L)in 1 cases of inflammatory pseudotumor, and the tumor markers were normal in other cases. One adenoma case underwent radiofrequency ablation and one hepatic tuber?culosis case did not undergo tumor resection and other cases underwent liver lesions complete resection(including local resection andhepatic segmental resection). Conclusion The rare liver tumors are difficult to diagnose preoperatively, and the misdiagnosis rate ishigh. Diagnosis is mainly based on the pathological indicators. Surgery is the main therapy for rare liver tumors or tumor?like lesions.
