1/56. Erosive adenomatosis of the nipple in an eight-year-old girl.Erosive adenomatosis of the nipple (EAN) is a rare, benign neoplasm of breast lactiferous ducts. Peak incidence is in the fifth decade in women. Clinically, it may be mistaken for Paget's disease and, histologically, for adenocarcinoma. Some authors have proposed an association with breast carcinoma and fibrocystic breast changes. Erosive adenomatosis of the nipple is extremely rare in children. Treatment is usually local excision of the nipple. This is the first formal English language case report of EAN in the pediatric age group. It is important for dermatologists to be familiar with this entity to prevent unwarranted breast removal.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/56. Radial scar of the breast.Four cases of radial scar of the breast, primarily diagnosed as carcinoma are presented; the patients were found among 858 patients who were operated on at our breast Unit over the last 4 years. The lesion was revealed on routine mammographic examination in 4 of our patients, while in the fourth it was found by palpation. In two of our patients mammographic examination revealed architectural distortion, in one patient micro-calcifications and in the fourth patient a stellate lesion was found. In the last two patients the lesion was localized before surgery with a hook wire. diagnosis was established by histopathologic examination in all cases. The surgeon, the radiologist and the pathologist should be aware of this clinical entity which, in spite of its benign character, has the ability to simulate invasive carcinoma clinically, mammographically and histopathologically.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
3/56. Atypical medullary carcinoma of the breast with cartilaginous metaplasia in a patient with a BRCA1 germline mutation.We examined a 34-year-old premenopausal woman who had noticed a left-breast lump a month previously. She had no past history of malignancies but had a family history of breast and ovarian cancers. Her mother had suffered from ovarian cancer when aged 47 years and had died of the disease at age 52. The younger two of the patient's four aunts had developed breast cancer when they were 37 and 48 years old. A physical examination showed an ill-defined mass, 1.5 cm in diameter, located in the upper outer quadrant of the patient's left breast. mammography revealed diffuse microcalcification in both breasts but ultrasonography revealed an irregular tumorous lesion only in the left breast. Aspiration breast cytology revealed adenocarcinoma of the left breast. Modified radical mastectomy of the left breast and excision of a biopsy specimen from the right breast were carried out simultaneously. Histopathologically the left-breast tumor was an atypical medullary carcinoma with cartilaginous metaplasia, of histological grade 3, and the right-breast specimen showed fibrocystic changes with atypical ductal hyperplasia. Estrogen receptors were positive, but progesterone receptor was not detected on the tumor cells, which were immunopositive for nuclear p53 although c-erbB-2 overexpression was not observed. A nonsense germline mutation of the BRCA1 gene (exon5) was detected. The patient has been well since the operation (10 months). These findings may provide useful information about the carcinogenesis and biological behavior of BRCA1-associated breast cancers.- - - - - - - - - - ranking = 3.4710296304822keywords = carcinoma, ductal (Clic here for more details about this article) |
4/56. Lobular carcinoma in situ in sclerosing adenosis.The initial presentation of breast malignancy as noninvasive carcinoma in an area of sclerosing adenosis is unusual. Especially, lobular carcinoma in situ in sclerosing adenosis sometimes can be a potential source of confusion with invasive lobular carcinoma. We report a case of lobular carcinoma in situ presenting in adenosis exhibiting patterns akin to invasive lobular carcinoma, thus leading to potential misdiagnosis. overall architecture of the lesion as seen at lower power and immunohistochemistry can be useful to distinguish between sclerosing adenosis with lobular carcinoma in situ and infiltrating lobular carcinoma.- - - - - - - - - - ranking = 5.5keywords = carcinoma (Clic here for more details about this article) |
5/56. Intracystic papillary carcinoma in the male breast. A case report.Male breast cancer is a rare disease with an incidence between 0.5% and 2.4% of that in women. We report a case of intracystic papillary carcinoma of the breast in a 75-year-old Japanese man. The macroscopic features of the carcinoma could be accurately demonstrated by pneumocystography and ultrasonography preoperatively.- - - - - - - - - - ranking = 3keywords = carcinoma (Clic here for more details about this article) |
6/56. Case of the Month. Giant multiple intraductal papilloma of the breast: a case report and review of the literature.A case is described of multiple intraductal papilloma of the breast in a 39 year old Micronesian female who presented to our institution with a 2 year history of spontaneous bloody nipple discharge with an associated giant cystic breast mass. This case report illustrates an unusual presentation of a rare benign breast lesion. The clinical, radiographic, and pathologic features of this disease process are discussed; the literature is reviewed; and management options are discussed.- - - - - - - - - - ranking = 2.355148152411keywords = ductal (Clic here for more details about this article) |
7/56. Suspicious node found at the time of reduction mammaplasty.A case of a patient with a suspicious glandular node found during reduction mammaplasty is described. The preoperative search for such nodes, the management of cases on which a suspicious node is found intraoperatively, and a situation on which the diagnosis of breast cancer is made during histology are discussed. When a suspicious small node (with a diameter up to 2 cm) is detected during a cosmetic breast surgery, lumpectomy can be performed. It may be a definite surgical treatment, depending on stage and tumor type. In the case presented, histology revealed intraductal papilloma, a benign tumor, therefore lumpectomy was a suitable procedure with an acceptable cosmetic result. With the increased incidence of breast cancer, this situation will happen more often and technical options for the management of such cases deserves the attention of plastic surgeons.- - - - - - - - - - ranking = 0.4710296304822keywords = ductal (Clic here for more details about this article) |
8/56. Cytologic findings of atypical adenosis of the breast. A case report.BACKGROUND: Atypical apocrine adenosis, a well-described histopathologic entity, can sometimes be misdiagnosed as carcinoma. Apocrine cells can also appear atypical in cytopathology and be mistaken for carcinoma. Occasional case reports describe false positive cases due to the presence of apocrine cells in a few cases of radial scars and atypical apocrine metaplasia and in a degenerated cyst. CASE: A 37-year-old female underwent ultrasound-guided fine needle aspiration of an ill-defined breast nodule. The aspirate showed clusters and single cells containing abundant granular to focally vacuolated cytoplasm; enlarged, pleomorphic nuclei with irregular nuclear membranes; granular chromatin; and prominent nucleoli. These cells were distinct from and larger than the surrounding ductal and myoepithelial cells. Excision showed a nodular area of atypical apocrine adenosis adjacent to previous biopsy changes, correlating with the cytologic findings. CONCLUSION: Atypical apocrine adenosis can mimic carcinoma in histopathology and cytopathology. One should be cautious when reviewing apocrine cells in cytology, given their atypical features, especially their single, dispersed nature. However, the presence of accompanying benign cellular elements supports a benign diagnosis. Surgical biopsy should be recommended based on the cytologic findings.- - - - - - - - - - ranking = 1.9710296304822keywords = carcinoma, ductal (Clic here for more details about this article) |
9/56. Microglandular adenosis of the breast in a BRCA1 mutation carrier: radiological features.Microglandular adenosis is a very uncommon benign proliferative disorder of the breast that may mimic tubular carcinoma radiologically and pathologically. We describe the radiological features of this rare condition in a patient with BRCA 1 mutation. To our knowledge, this is the first case of microglandular adenosis reported in the radiology literature. The relationship between microglandular adenosis and malignancy and the association between BRCA 1 and proliferative benign disorders are also discussed.- - - - - - - - - - ranking = 0.5keywords = carcinoma (Clic here for more details about this article) |
10/56. Intracystic papillary carcinoma of the breast in a male patient diagnosed by ultrasound-guided core biopsy: a case report.Male breast cancer is an uncommon disease with an incidence of approximately 1% of all breast cancers. We report a case of intracystic papillary carcinoma of the breast occurring in a 67-year-old man in whom the diagnosis was made by ultrasound-guided core biopsy. This report represents the first reported intracystic papillary carcinoma diagnosed by core biopsy and illustrates the cost-effectiveness of this technique in a male patient in providing diagnostic material and allowing for expeditious planning of definitive treatment.- - - - - - - - - - ranking = 3keywords = carcinoma (Clic here for more details about this article) |
