Background/aim: The study aimed at investigating the correlation between ductoscopic and histopathological findings and clarify whether the former allow for accurate prediction of malignancy., Patients and Methods: The prospective national multi-center study covered a sample of 224 patients with pathologic nipple discharge. A total of 214 patients underwent ductoscopy with subsequent extirpation of the mammary duct. The ductoscopic findings were categorized according to shape, number, color and surface structure of lesions and vascularity and compared to the histological results and analyses., Results: Ductoscopy revealed lesions in 134 of 214 patients (62.2%). The criteria "multiple versus solitary lesion" differed significantly between malignant and benign lesions. All other criteria were not statistically significant. Malignant tumors were more frequently presented as multiple lesions, benign lesions or masses as solitary lesions (80% vs. 24.8%; p=0.018)., Conclusion: The ductoscopic criterion "solitary vs. multiple lesion" appears to have a low diagnostic prediction of malignancy or benignity., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J.

Purpose: The aim of this study was to evaluate the quality standard of the nationwide breast ultrasound training program of the German Society of Ultrasound in Medicine (DEGUM) through objective parameters., Materials and Methods: 10 quality criteria, based on the recommendations of The National Association of Statutory Health Insurance Physicians (KBV), were defined for this study. All training units of the DEGUM received a questionnaire. The questionnaires and training material were analyzed., Results: All units met the required criteria pertaining to the trainer's qualification, duration per training course and the maximum number of participants per ultrasound machine. Only 1 course did not fulfill the required 50 % practical training time. The requirements to participate in the graduate course (200 self-made and documented cases) were not clearly conceived and a defined training log could be improved., Conclusion: DEGUM breast ultrasound training offers trainees a high level of education based on the requirements of the KBV. Despite the high quality of training, the content of course announcements could be improved and an official and structured educational index could be meaningful., (© Georg Thieme Verlag KG Stuttgart · New York.)
