The pathological changes of the tumor tissue after photodynamic therapy in nude mice bearing human hepatocellular carcinoma were observed under light microscope. The histopathological changes of liver biopsy specimens and surgical specimens after photodynamic therapy of human primary hepatocellular carcinoma were observed. Results In the photodynamic group of 15 human hepatocellular carcinoma mouse models, tumor cells were extensively necrotic; in the control group, no tumor cell necrosis was observed. Thirty patients with hepatocellular carcinoma underwent liver biopsy and tumor cells appeared after photodynamic therapy
