RESUMEN
Six cases of cervical adenocarcinoma with plentiful mucous secretion were recently experienced. They were clearly distinguishable from the majority of adenocarcinoma without plentiful mucous secretion from the standpoint of clinical and colposcopic findings. As common features deduced from clinical and colposcopic findings, it could be pointed out that portio vaginalis become swollen as a whole showed resiliency as of a rubber ball, and that erosion widespread over nearly entire surface of portio vaginalis is accompanied with a plentiful mucus. On the surface of erosion was found neither localization of ulcer, nor necrosis and nor bleeding trend even in cases under progressing. Colposcopic findings were distinguished with features of papillea-, net-and transformation zone-like, and mixed type. On the other hand, all the cases were evaluated cytologically to be positive with difficulty. And they were histologically well differentiated adenocarcinoma with plentiful mucus. The distinctive feature in the clinical and colposcopic findings identified for the cases of well differentiated adenocarcinoma with a plentiful mucus was evaluated to be useful means to assist the diagnosis of cervical adenocarcinoma.
