The term ductal adenoma has been recently introduced to describe a solid benign lesion of breast ducts. This study describes the clinical, morphologic, and immunohistochemical features of 15 cases of ductal adenoma. Ductal adenomas are usually single, occasionally multiple, lesions occupying medium- and large-sized breast ducts. They may occur in women of all ages, although the majority of patients are 60 years of age or greater. Ductal adenomas usually present clinically as breast lumps which may mimic carcinoma; less commonly, they are associated with nipple discharge. Patients in this series showed no family or previous history of breast disease and had uneventful follow-up after local excision. Despite often showing worrying pseudoinfiltration and cytologic atypia, the immunohistochemical demonstration of a myoepithelial layer and intact basement membrane around the tubules was clear evidence of the benign nature of the lesions. We conclude that most ductal adenomas evolve by sclerosis of benign intraduct papillary lesions, although processes similar to sclerosing adenosis and, possibly, duct ectasia may contribute to the pathogenesis of a proportion of cases. It is hoped that a wider appreciation of the entity of ductal adenoma will reduce the diagnostic uncertainty that continues to surround these and related lesions.

Twenty-four cases of a solid benign tumour of breast ducts are described, for which we propose the name 'ductal adenoma'. The lesion consists of a single nodule or multiple nodules involving medium size and small ducts, but not major subareolar ducts. It presents as a palpable lump, and is not associated with a nipple discharge. Clinically, radiologically and macroscopically, it can simulate malignancy because of its occurrence in older age groups, frequent microcalcification and the firmness and irregularity of many lesions. Fibrous sclerosis sometimes results in distortion with apparent invasion of surrounding tissue. It can be mistaken for carcinoma both on frozen and paraffin sections. Differentiation into epithelial and myoepithelial cells is the most reliable criterion in the recognition of this lesion as benign. It has microscopic affinities with ductal papilloma, on the one hand, and with salivary-type adenoma, on the other. Ductal adenoma constitutes the third major type of adenoma in the breast, in addition to the already widely recognized nipple adenoma and tubular adenoma.

In case of abnormal nipple discharge of the female breast galactography is a recognized radiological procedure to identify and to localize intraductal growths or other ductal abnormalities. However, it harbours several methodological problems. In ductal orientated sonography the availability of high frequency linear transducers enables us now to visualize the mammary ducts in detail. The aim of this study was to compare both methods with respect to the detection of the cause of pathological nipple discharge. Thirty-five patients were first examined by ductal orientated sonography with a 13 MHz linear transducer. The results of sonography were recorded in detail before galactography was performed. Ductal abnormalities were found by sonography in 26 patients and by galactography in 19 patients. In 24 cases both methods revealed concurring results. Among those, 17 cases showed pathological findings and seven cases had normal ducts. In nine patients sonography revealed pathological results whereas galactography was completely normal. In only two cases sonography failed to show ductal abnormalities which were detected by galactography. Our study underlines that ductal orientated sonography is a promising method of diagnosis in abnormal nipple discharge, which may be recommended to be performed routinely before galactography.

Bloody nipple discharge causes a high degree of anxiety in women because of fear of breast cancer. Commonly, the absence of palpable or mammographic abnormalities gives a false sense of security, causing delays in diagnosis. Initial evaluation with physical examination and mammography is useful in detecting high-risk cases. Bloody nipple discharge is most frequently benign. It is caused by intraductal papilloma, duct ectasia, and less frequently by breast cancer. Several diagnostic tests have been proposed to establish the cause of bloody nipple discharge. Galactography, ultrasound, and exfoliative cytology are useful only when positive, but have a high rate of false-negative results and do not preclude histologic diagnosis. More recently, ductal lavages in combination with cytology have provided promising results, but experience and long-term follow-up are limited. Traditional treatment is surgical excision of the involved ductal system from which the discharge emanates. Ductal excision has been the only reliable procedure in establishing a certain diagnosis and in controlling the bloody discharge. The early success reported with image-guided excision of papilloma and duct endoscopy promises a significant improvement in our diagnostic accuracy from minimally invasive emerging technology.

Breast carcinoma and hyperplasia are thought to start in the lining of the breast duct. Mammary ductoscopy is an emerging technique allowing direct visual access of the ductal system of the breast through the nipple. This article reviews and discusses the utility of mammary ductoscopy. Abnormalities can be identified successfully by mammary ductoscopy, and intraductal biopsy can be used when the tumor is a polypoid type. Ductal lavage using microcatheters is effective in identifying malignant cells in high-risk women and this has stimulated interest in exploring the role of mammary ductoscopy in breast cancer screening. Mammary ductoscopy combined with ductal lavage may have a role in the management of patients with nipple discharge, the guiding of breast-conserving surgery for cancer, and in screening for high-risk women. The addition of molecular and genetic analysis of cells obtained by mammary ductoscopy are likely to enhance the use of this technique. Mammary ductoscopy techniques are safe and appear useful for detecting abnormalities in the breast. The additional molecular biologic study or ductal lavage may enhance the ability to direct and limit subsequent surgery when removing the offending lesions.

With increasing emphasis on public awareness of breast cancer and screening mammography, more women seek consultation for breast symptoms, including nipple discharge. The presence of nipple discharge is distressing for the patient; however, its origin is fortunately most often benign. Nipple discharge associated with a recognizable mass requires sampling and surgical excision. Currently, clinical breast examination, cytology, ductography, mammogram, and ultrasound are commonly used to evaluate patients who have nipple discharge. Ductal lavage and ductoscopy, in association with emerging new technology, may be of help in increasing the sensitivity of nipple fluid cytology. In addition, nipple fluid cytology may offer a new way to study the spectrum of premalignant breast lesions, and to identify women at risk for breast cancer.

Ductitis obliterans or mastitis obliterans is a rare late manifestation of mammary ductal ectasia. We describe a long-term diabetic patient who presented with bilateral bloody nipple discharge and poorly defined nodularities around the nipple of both breasts. The ductography showed multiple segments of irregular ductal narrowing and intraluminal filling defects in both breasts. The bilateral resection of the sub-areolar portion of the breast showed exuberant fibrous obliteration of the large- and medium-sized ducts by granulation tissue associated with few histiocytes. Ductal dilatation and intraductal accumulation of histiocytes was also present. This represents a late and florid form of mammary ductal ectasia. Differential diagnostic considerations including fibrocystic changes, diabetic sclerosing lymphocytic lobulitis, idiopathic granulomatous lobular mastitis, and periductal mastitis (Zuska disease) are discussed. Accurate diagnosis can help avoid or limit radical surgeries in this group of patients.

Mammary ductoscope allows visualization of the breast ductal wall and sampling of the abnormal area for diagnostic purposes. We are reporting our center experience in application of mammary ductoscope in detecting the underlying etiology of pathologic nipple discharge. Between November 2005 and December 2006 a total of 54 women, with spontaneous persistent nonlactational unilateral uniductal nipple discharge of no palpable lesions and negative breast sono-mammography, were included in the study for morphologic assessment of ductal epithelium, ductal lavage and ductoscopically guided procedures as punch biopsy and ductoscopically guided microdochectomy. Forty-one patients (76%) with nipple discharge were positive ductoscopically. Thirteen patients (24%) appeared normal. Ductoscopic lavage has a much more cellular yield than ordinary squeezing cytology. Ductal thickening by the ductoscope (11 cases) revealed to be hyperplasia on pathology (five cases), papilloma (two cases), atypical ductal hyperplasia (two cases), ductal carcinoma in situ (one case), and invasive breast carcinoma (one case). There was a significant association between intraductal visual observations and histopathologic diagnosis. Mammary Ductoscope is a promising tool in management of pathologic nipple discharge. Biopsy and ablation techniques can be performed during ductoscopy with correlation between visual findings and histopathology, but there are still some limitations of in clinical practice.

Until recently, the mammary duct had not been directly observed in vivo. Starting with the success of Teboul et al., studies of mammary ductoscopy (MD) for nipple discharge have been performed in Japan and other East Asian countries. Ductal lavage screening trials for breast cancer started in the 2000s. Concurrently, the number of English-language articles about MD increased. Sixty-nine English-language and 74 Japanese-language papers published in the last 19 years were reviewed. Important reports and studies were analyzed. MD has undergone significant technological development, and studies of MD have taken place in many countries. As a result, endoscopic images of the mammary duct have developed, and the endoscopic diagnosis for nipple discharge has become possible. MD-guided biopsy and surgery have been studied. Findings of MD are useful for diagnosing intraductal lesions with nipple discharge. As a result, MD has reduced the number and extent of microdochectomies. MD is also helpful in guiding breast-conserving surgery. Many pioneers have tried direct biopsy or interventions under MD, but further developments are necessary for its practical use.
