RESUMO
Objective To discuss the diagnosis and treatment of intraductal papillomatosis. Methods Fifteen cases of intraductal papillomatosis were analyzed retrospectively. Results Of the 15 cases,preoperative diagnosis of intraductal papillomatosis was made in 8 cases who had received fiberoptic ductoscopy,while the rest of 7 cases who had not undergone ductoscopy were wrongly diagnosed.Postoperative pathological findings revealed 2 cases of partial malignant change and 1 case of contralateral infiltrating lobular carcinoma.Reoperation was required in 3 cases because of relapse,the relapse rate being 20%. Conclusions Intraductal papillomatosis is absolutely different from intraductal papilloma.It presents the potentiality of malignancy,and is subject to relapse after local resection.Fiberoptic ductoscopy may improve the diagnosis rate for this disease.
