New cervicoscopy with toluidine blue staining for superficial cervical invasion by endometrial carcinoma.
We developed a method of endocervical staining with toluidine blue solution during cervicoscopy that clearly discriminates between the endocervical region and the endometrium and allows easy detection of superficial cervical invasion by endometrial carcinoma. Toluidine blue staining cervicoscopy was used for preoperative histological diagnosis in 10 cases of endometrial carcinoma. The staining permitted a correct diagnosis in 3 cases in which conventional diagnostic methods were practically useless. Endocervical staining with toluidine blue is highly useful for diagnosis of superficial cervical invasion by endometrial carcinoma.
