This study was aimed at determining the role of high-frequency (7.5 MHz) US combined with cytology in the diagnosis of complex breast nodules (complex cysts--cystic tumors). The study population included 60 patients presenting with complex breast nodules selected on the basis of US patterns among 3,000 cases. All patients were also submitted to US-guided fine-needle aspiration biopsy (FNAB). Cytology of nipple discharge was always performed when discharge was present (15 cases), mammography was performed in 50 cases and pneumocystography in 10. US allowed the identification of the lesion in all patients and the diagnosis of nature in 73%; with FNAB the figure reached 96.7%. Mammography identified the lesion in 95% of patients, but failed to reveal the complex nature of the nodule. In a small number of cases mammography proved to be a useful complementary tool demonstrating malignant features not recognizable on US images. On the contrary, pneumocystography yielded no further information with respect to US. Diagnostic control was obtained by means of surgery in 30 patients and of clinical-US follow-up in the extant 30 cases. On the basis of their US features the lesions were classified into two groups: I) nodules having a mainly liquid component--i.e., hemorrhagic, septic, multilocular cysts, papillary cystadenoma; II) nodules having a mainly solid component--i.e., solitary intraductal papilloma, intracystic carcinoma, mixed carcinoma, phylloid adenoma, sarcoma. As to the former group, US proved reliable in making a diagnosis in the cases with typical hemorrhagic, septic and multilocular cysts. In the atypical cases, FNAB of the solid component of the nodule was necessary to differentiate irregular clots, thick septa or inflammatory thickening from different conditions. As to the latter group, FNAB of the solid component and/or mammography proved useful in making a diagnosis, even though to this aim US revealed peculiar patterns which were highly suggestive. In our experience, combined US and FNAB are of basic importance in the diagnosis of breast lesions, thus replacing pneumocystography which has been widely employed so far. As regards mammography, its role seems limited to pointing out the peculiar characters of malignancy which could not be demonstrated otherwise.

The features of ductal adenoma of the breast, a solid intraductal tumor, include the following: arrays of long, straight, narrow, roughly parallel tubules composed of distinct epithelial and myoepithelial cells; a modest amount of fibrous tissue that separates the ducts from one another; and a fibrous capsule. We found this neoplasm in four women (ages 27 through 61 years) who had the complex of myxomas, spotty pigmentation, endocrine overactivity, and schwannomas, an autosomal dominant familial syndrome. The lesion was bilateral in two of the women. Each of the patients had mammary myxoid mesenchymal lesions typical of the complex. Two tumors were symptomatic (bloody nipple discharge); the four others were not. Five of the six tumors formed palpable masses that were located close to the areola. The mammograms suggested carcinoma. On microscopic examination, four of the six adenomas were mistaken for carcinoma; none recurred or metastasized. Circumstantial evidence suggests that the ductal adenoma of the breast is a component of the complex of myxomas, spotty pigmentation, endocrine overactivity, and schwannomas.

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.

A syringomatous adenoma of the nipple is a benign locally infiltrating neoplasm histologically similar to the syringoma of the skin. Morphologically similar lesions have been described as adenoma of the nipple or florid papillomatosis. Patient was a 33 year old woman who was admitted with a history of bloody nipple discharge from her right breast. With a clinical impression of Paget's disease explorative mastectomy was performed. Microscopically typical tubular and duct like structures with syringomatoid features were present throughout the stroma of the nipple.

Sclerosing papillary duct hyperplasia occurs in various locations in the breast. In the nipple, the process produces a distinct clinicopathological entity referred to as nipple adenoma or florid papillomatosis (FP). Peripheral lesions have been termed radial scar and nonencapsulated sclerosing lesions. This report describes 12 women who presented with sclerosing papillary duct hyperplasia in the subareolar portion of the breast. The term subareolar sclerosing duct hyperplasia (SSDH) is proposed for this condition. The average age of the patients was 46 years (26-73 years). None of the lesions, which averaged 1.2 cm (0.6 to 2.0 cm), involved the nipple. All were beneath the nipple and/or areola or in the breast close to the areola. Three women had bloody nipple discharge but none had nipple erosion or other signs suggestive of Paget's disease. Five patients were well 9 months to 3 years, 9 months (average, 2 years, 7 months) after excisional biopsy. Two other patients had persistent SSDH reexcised 2 years, 6 months and 2 years, 10 months, respectively, after diagnosis. Both were well 1 year later. There is no follow up in two patients treated by excision. Three women are well after treatment by mastectomy. In one of those patients, intraductal carcinoma was found arising in SSDH. The clinical presentation of SSDH differs sufficiently from other proliferative duct lesions to warrant considering it a distinct disease process. It does not appear to be associated with a particular proclivity to evolve into carcinoma and short-term follow-up suggests that excisional biopsy is probably adequate therapy.

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.

Spontaneous single duct discharge is the main indication for galactography. This abnormality has in most cases a benign aetiology (> 90%). With a meticulous technique and sufficient experience, the ducts can be cannulated in 95% of the cases. A nipple adenoma with a blood stained discharge is seldom to pass for cannulation. Because cytology of the nipple discharge is not always positive in case of intraductal proliferations, microdochectomy must be used to obtain the differential diagnosis. Galactography shows multiple normal duct variations, depending on age, surrounding tissue, and a possible history of lactation. Pathologic images can be seen in dystrophic breasts, solitary papillomas, (juvenile) papillomas or (intraductal) carcinomas. In addition to high frequency ultrasonography (> or = 10 MHz), which is able to visualise the retro-areolar and superficial ducts, galactography can give a more detailed and better overview of the pathology.

Although carcinoma of the breast complicates 1:3000 deliveries in the US, most breast conditions unique to pregnancy and lactation are benign--for example, lactating adenoma, galactocele, gigantomastia, and benign bloody nipple discharge. Nevertheless, malignancy must be excluded by a thorough work-up, including breast biopsy if indicated; "watchful waiting" when a breast mass is discovered is no more appropriate than in a nonpregnant patient. During lactation, the major problems encountered often are part of a spectrum of inflammatory and infectious complications. Nasopharyngeal organisms from the infant are usually the source of breast infections in lactating women. Keeping the breast empty of milk promotes healing by helping to drain the culture medium that is facilitating growth of organisms. Hence, the earlier recommendations that breast-feeding cease during mastitis have been superseded by the knowledge that breast-feeding is generally not harmful to the infant and may speed resolution of the infectious process. The diagnosis and management of pregnancy-associated breast cancer (PABC) is reviewed. Pregnancy-associated masses are usually discovered by patient self-examination, and the clinician should proceed to fine-needle aspiration or biopsy, rather than mammography, which has poor sensitivity during pregnancy and lactation because of increased breast density. Management of a new breast mass in pregnancy should maximize diagnostic accuracy and minimize the chances of missing PABC, yet avoid harm to the fetus or interruption of lactation.

A case is presented, where a 52 year-old woman with a two month history of nipple discharge was diagnosed with adenoma of the nipple. A total excision of the nipple was performed. Adenoma of the nipple is a rare, but benign condition, which clinically can be confused with Paget's disease of the nipple, intraductal papilloma and adenocarcinoma of the breast. Complete excision of the nipple is an adequate treatment of this condition.

We recently treated a 14-year-old girl with a clinically and histologically diagnosed with adenoma of the nipple. Enucleation of a mass preserving the nipple was successfully performed. Adenoma of the nipple is a rare disease which is often mistaken clinically for Paget's disease. About 200 cases of the tumors have been reported worldwide so far. The most common symptom is erosion of the nipple and nipple discharge. Our case had erosion of the nipple but no discharge. Adenoma of the nipple is a benign lesion which can be successfully treated by a simple surgery.
