Note the prominent vascularity as well as the area of necrosis at the left with neoplastic cells palisading around it. 注意典型的血管构成,如图左边坏死区域肿瘤细胞呈栅栏状围绕。
They were mainly consisted of epithelia differentiated towards cells of the outer root sheath, and the peripheral basal cells of the tumor lobules showed palisading arrangement. 组织病理学检查示肿瘤呈分叶状增生,与表皮相连,主要由向外毛根鞘分化的鳞状上皮组成,周边基底细胞排列成栅栏状。
The histopathological study showed that palisading granuloma pattern accounted for 71.7% in all patients, and scattered histiocytic infiltration accounted for 28.3%. 组织学改变以栅栏状肉芽肿最常见(占71.7%),散在性组织细胞浸润次之(占28.3%)。
