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 re gion 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 ca rcinoma. The staining permitted a correct diagnosis in 3 cases in which con ventional diagnostic methods were practically useless. Endocervical stainin g with toluidine blue is highly useful for diagnosis of superficial cervica l invasion by endometrial carcinoma. Copyright (C) 2000 S. Karger AG, Basel .
