the pathological bases were related to necrosis, cyst degeneation, hemorrhage, and hemosiderin deposition etc.
其病理基础主要与肿瘤内坏死、囊变、出血、含铁血黄素沉着等病理改变较多有关。
sixty percent of the tumors were accompanied with calcification, 35% with ossification, 25.5% with hemosiderin or melanism.
病例伴有钙化,35%有骨化,25.5%有含铁血黄素或黑色素沉着。
the resolution left behind hemosiderin from the hemorrhage that produces the orange-brown staining.
出血后血液溶解形成的含铁血黄素产生棕黄色外观。
the hemosiderin from the hemorrhage produces the grossly brown color.
出血形成的血铁黄素使病变肉眼观察呈深棕色。
prussian blue reaction is seen in this iron stain of the liver to demonstrate large amounts of hemosiderin that are present in hepatocytes and kupffer cells.
