Intraductal papillomatous lesions in the breast may be manifestations of different histological types of tumors, including papillomas and intraductal papillary carcinomas. Intraductal papillomas are relatively rare, with an incidence of 2-3%. They are benign tumors that arise from the mammary duct epithelium. We observed a tumor of this type in a 51-year-old woman who had noted bloody discharge from her right nipple. She was referred for breast sonography a few days later.The sonographic examination revealed a dilated duct enclosing a mass, which was surgically removed. Histological examination revealed that the lesion was benign (intraductal papilloma).This case illustrates the role of imaging in confirming clinical diagnoses of papillomatous lesions. Histological confirmation is always necessary, however, to rule out the presence of intraductal papillary carcinoma.
乳腺导管内乳头状病变可能是不同组织学类型肿瘤的表现，包括乳头状瘤和导管内乳头状癌。导管内乳头状瘤相对少见，发病率为2%-3%。它们是起源于乳腺导管上皮的良性肿瘤。我们在一名51岁女性中观察到了这种类型的肿瘤，该女性注意到右侧乳头有血性溢液。几天后她被转诊进行乳腺超声检查。超声检查发现一个扩张的导管内包有一个肿块，该肿块被手术切除。组织学检查显示该病变为良性（导管内乳头状瘤）。这个病例说明了影像学在证实乳头状病变临床诊断中的作用。然而，为了排除导管内乳头状癌的存在，组织学确认始终是必要的。
