目的研究小肝癌的病理形态。方法小肝癌７例，进行了光镜水平观察研究。结果高分化型肝癌６例，癌细胞呈条索状，癌细胞浆内可见到脂肪滴或呈透明样染色改变。中分化型１例，癌细胞呈现出假腺管样排列。结论小肝癌多为高分化型肝癌，与进展期肝癌不同。进行病理诊断时，应与腺瘤样增生及肝腺瘤等病变鉴别。
Objective To study the pathological features of small hepatocellular carcinoma. Methods Seven cases of small hepatocellular carcinoma were observed under light microscope. Results There were 6 cases of well-differentiated liver cancer. The cancer cells showed a cord-like appearance, and lipid droplets or clear staining showed changes in the cancer cells. In 1 case of moderately differentiated type, the cancer cells showed a false gland-like arrangement. Conclusions Small hepatocellular carcinoma is a well-differentiated hepatocellular carcinoma, which is different from advanced hepatocellular carcinoma. Pathological diagnosis should be differentiated from adenomatous hyperplasia and hepatic adenoma.
