Forty-six patients with villous or tubulovillous tumors of the colon were examined to study the correlation between histologic and macroscopic or radiographic features and to define more accurately villous tumors of the colon. There was good correlation between the histologic and macroscopic or radiographic features. As villous elements became more prominent on histologic studies, the macroscopic appearance was more villous and granular but less nodular on the surface. Reticular and/or granular patterns with a feathery margin were more frequently seen on radiographs in cases of dominant villous elements. The macroscopic and radiographic characteristics of villous tumor frequently appeared when villous elements composed over 75% of the whole tumor on histologic studies. The authors propose that villous tumor of the colon can be accurately diagnosed when villous elements compose over 75% of the tumor.
对46例结肠绒毛状或管状绒毛状肿瘤患者进行检查，以研究组织学特征与大体或影像学特征之间的相关性，并更准确地界定结肠绒毛状肿瘤。组织学特征与大体或影像学特征之间存在良好的相关性。在组织学研究中，随着绒毛成分变得更加突出，大体外观更呈绒毛状和颗粒状，但表面结节较少。在以绒毛成分为主的病例中，X线片上更常出现边缘呈羽毛状的网状和/或颗粒状图案。当组织学研究显示绒毛成分占整个肿瘤的75%以上时，绒毛状肿瘤的大体和影像学特征经常出现。作者提出，当绒毛成分占肿瘤的75%以上时，可准确诊断结肠绒毛状肿瘤。
