Two of three patients with erythropoietic protoporphyria showed pigment deposits with typical red porphyrin fluorescence on liver biopsy specimens. Birefringence of this pigment by polarized light is due to its crystalline nature, as demonstrated by electron microscopy. There was slight portal inflammation in these cases. A liver biopsy specimen from a third patient was normal.
三名红细胞生成性原卟啉症患者中有两名在肝活检标本上显示出具有典型红色卟啉荧光的色素沉着。如电子显微镜所示，这种色素在偏振光下的双折射是由于其晶体性质。这些病例中存在轻微的门管区炎症。第三名患者的肝活检标本正常。
