1/22. carcinoma of the axillary breast.Axillary breast is one of the varieties of polymastia which is characterized by the presence of more than 2 breasts. It may cause symptoms during pregnancy, lactation, or in the premenopausal period. Unless there are obvious symptoms of lactation or the assistance of further imaging studies such as mammography and breast ultrasound, the diagnosis is often confused with subcutaneous lipoma. The incidence of axillary breast cancer is low but it should be investigated and treated properly in view of another breast cancer in the embryonic milk-line. In this paper we reviewed 4 cases of axillary breast cancer and documented some articles regarding aberrant breast and carcinoma arising from it. It is suggested that subcutaneous nodules of uncertain origin around the periphery of the breast should be viewed with suspicion and treated properly.- - - - - - - - - - ranking = 1keywords = lactation (Clic here for more details about this article) |
2/22. F-18 FDG uptake in breast infection and inflammation.PURPOSE: Whole-body fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET) scanning has been useful in the management of breast cancer. However, F-18 FDG uptake sometimes has been associated with benign breast disease. Four cases are reported of F-18 FDG breast uptake caused by infectious or inflammatory mastitis that mimics malignant disease. methods AND RESULTS: Two women had F-18 FDG whole-body scans for the evaluation of a large breast mass after inconclusive results of ultrasonography. In both cases, intense focal F-18 FDG breast uptake was noted that mimicked breast cancer. Histologic examination showed, in one patient, chronic granulomatous infiltration that likely represented tuberculous mastitis, because she showed a good clinical response to empirical anti-tuberculous treatment. The second patient had lactational changes associated with acute inflammation, and the culture grew staphylococcus aureus. The breast mass completely disappeared 3 weeks after a course of antibiotic treatment. The other two patients had staging F-18 FDG PET scans 1 and 12 months after lumpectomy for breast carcinoma to detect residual, recurrent, or metastatic disease. Both scans showed a ring-like uptake in the involved breast, with superimposed intense focal uptake suggesting tumor necrosis centrally and malignant foci peripherally. In both cases, histologic examination revealed hemorrhagic inflammation secondary to postsurgical hematomas and no evidence of malignancy. CONCLUSION: Acute or chronic infectious mastitis and postsurgical hemorrhagic inflammatory mastitis should be considered in patients who have a breast mass, especially those with a history of tenderness or surgery.- - - - - - - - - - ranking = 0.5keywords = lactation (Clic here for more details about this article) |

4/22. breast carcinoma presenting during or shortly after pregnancy and lactation.CONTEXT: Much has been written about the clinical management and prognosis of breast carcinomas presenting during pregnancy and lactation, yet little is known about the detailed histopathology of these tumors. OBJECTIVE: To determine whether these carcinomas have any specific diagnostic features. DESIGN: A detailed histologic and immunohistochemical study of 14 cases of breast carcinoma presenting during or shortly after pregnancy or lactation was conducted. The findings were compared with a control group of 13 tumors developing in age-matched women with no recent history of pregnancy or lactation. SETTING: The histopathology department of a tertiary referral teaching hospital. RESULTS: Tumors in the pregnancy/lactation group had a significantly higher incidence of cancerization of lobules (79% vs 15%) and of grade III invasive ductal carcinomas (80% vs 33%). Tumors occurring during lactation were either totally or partly mucinous and were MUC2 positive. Tumors occurring during pregnancy, but not during lactation, were mostly estrogen and progesterone receptor negative (4/5 and 5/5, respectively). All tumors occurring during pregnancy and lactation that were tested for c-erbB-2 overexpression were negative, whereas all 4 tumors tested that occurred shortly after delivery or cessation of lactation were positive for c-erbB-2 overexpression. The incidence of axillary lymph node metastasis was high in both the study and control groups, although it was slightly higher in the control group (78% and 90%, respectively). CONCLUSIONS: Although breast carcinomas diagnosed during or shortly after pregnancy and lactation have features in common with those developing in women of similar ages, particularly with respect to a high incidence of lymph node metastasis, the findings of this study suggest that they may also have distinct morphologic and immunohistochemical features of their own. Such features may vary according to whether the patient was pregnant, lactating, or had recently terminated her pregnancy or lactation at the time of surgical excision. Examination of more cases would help confirm these findings.- - - - - - - - - - ranking = 7keywords = lactation (Clic here for more details about this article) |
5/22. Primary squamous cell carcinoma of the breast during lactation: a case report.A case of primary squamous cell carcinoma of the breast during lactation is reported. The patient was a 32-year-old woman, in post-partum lactating 18 months after delivery, who was referred to our hospital following detection of a lump in her left breast during physical examination in mass screening for breast cancer. The tumor, palpated in the upper outer quadrant of the left breast, was firm, well-defined and 2.8 x 2.6 cm in size. Ultrasonograms identified an irregular-shaped hypoechoic lesion and mammograms revealed a well-defined, circumscribed tumor. Based on these findings, breast cancer was suspected and an excisional biopsy was performed. The resected specimen was a firm, solid and circumscribed tumor with central hemorrhage. Microscopic findings demonstrated that the tumor consisted of an invasive ductal carcinoma with marked squamous metaplasia, such as keratinization and squamo-columnar junction. breast-conserving surgery was performed and no lymph node involvement was noted. Both estrogen and progesterone receptors of the tumor were negative. Generally, the size of both squamous cell carcinoma and carcinoma during the lactation period tends to be larger than ordinary carcinomas. In this case, the cancerous lesion was detected at a relatively early stage. Although the cancerous lesion was detected at a relatively early stage and no lymph node involvement was noted, lung metastases occurred within 12 months of the surgery. Malignant potential is generally considered to be high in cases of squamous cell carcinoma of the breast with lactation and thus intensive treatment potentially resulting in severe side effects was considered to be necessary for this patient.- - - - - - - - - - ranking = 3.5keywords = lactation (Clic here for more details about this article) |
6/22. MALT lymphoma originating in breast and uvula.A case of marginal zone B cell lymphoma of MALT type arising in the uvula and breast is reported. The patient, a 30-year-old woman who delivered a child and lactated in 1997, was suffering from Sjogren syndrome (SS). She was diagnosed with MALT lymphoma after a biopsy of the right breast and uvula. To investigate the relationship of the delivery, lactation and MALT lymphoma, we examined the immunohistochemical analysis of hormone receptors. As a result, lymphoid cells of the breast were stained with anti-progesterone receptor antibodies in the cytoplasm. Consequently, the MALT lymphoma of the uvula appeared to be associated with SS. Moreover, hormones such as progesterone may have influenced the breast involvement of MALT lymphoma in our case.- - - - - - - - - - ranking = 0.5keywords = lactation (Clic here for more details about this article) |
7/22. Lactating adenoma: a diagnosis of exclusion.This is a case of a large lactating adenoma which developed in a 26 year old primagravida during the third trimester of her pregnancy. The presentation was that of a grossly enlarged and engorged breast with breast erythema, warmth and tenderness. Radiologic and pathologic examinations were difficult because of the lactational changes in the breast and areas of infarcted tissue within the large tumor. skin biopsies and core biopsies of the mass were performed to exclude malignancy. Surgical resection of the mass was necessary for definitive diagnosis. The pathology proved to be a lactating adenoma, which is the most prevalent breast mass in young pregnant females. The large size of this tumor, and the presentation of breast erythema and edema raised the possibility of inflammatory breast cancer. Following surgical resection and definitive diagnosis of this tumor, the patient required plastic surgical reconstruction of the breast because of redundant breast tissue. Although most lactating adenomas spontaneously involute, the diagnosis is not always straight-forward and surgical resection may be required for definitive diagnosis and exclusion of other pathologic processes.- - - - - - - - - - ranking = 0.5keywords = lactation (Clic here for more details about this article) |
8/22. Lactating adenoma--cytomorphologic study with review of literature.Lactating adenoma is an uncommon well-differentiated benign tumor of secretory mammary epithelium that occurs in pregnant and lactating women. Three percent of all breast cancers are diagnosed during pregnancy and need to be differentiated from other breast masses occurring in pregnancy and lactational states. Its origin, though controversial, is believed to be de novo or a variant of pre-existing tubular adenoma or fibroadenoma, that reflects the morphologic changes resulting from the physiologic state of pregnancy. Four pregnant/lactating women presenting with solitary breast masses were aspirated. Spontaneous regression of the mass was observed in two of the four cases, one underwent excision biopsy and one case was lost to follow up. All four cases were diagnosed as lactating adenoma on fine needle aspiration cytology. Cytomorphologic features included cellular aspirates comprising of epithelial cells, scattered and in small groups. The acinar cells had foamy to vacuolated cytoplasm. The nucleus had prominent nucleoli. Background showed abundant foamy material. biopsy confirmed lactating adenoma in one of the cases. Lactating adenoma needs to be differentiated from other breast masses, including carcinoma, in pregnant or lactating women. Sonographic studies are not diagnostic and surgical biopsies are not recommended as a majority of the lesions are known to regress spontaneously.- - - - - - - - - - ranking = 0.5keywords = lactation (Clic here for more details about this article) |
9/22. Infarcted myxoid fibroadenoma following fine-needle aspiration.infarction of breast fibroadenomas is very rare and is frequently associated with physiologic changes, such as pregnancy and lactation. We report a case of an infarcted fibroadenoma following fine-needle aspiration. The patient presented with an asymptomatic breast mass, which was clinically difficult to evaluate. Excisional biopsy was performed 7 days after a nondiagnostic fine-needle aspiration of the mass. Microscopically, the nodule showed features of a classic fibroadenoma of the intracanalicular type with myxoid or mucinous stromal changes, as well as extensive areas of acute infarction. This report provides another example of the changes that may be observed in biopsy specimens obtained after fine-needle aspiration of the breast.- - - - - - - - - - ranking = 0.5keywords = lactation (Clic here for more details about this article) |
10/22. Galactorrhoea following acupuncture.A 41-year-old woman with breast cancer was referred to the pain management clinic for a course of acupuncture for intense pain following a subcutaneous mastectomy and a latissimus dorsi flap reconstruction. She was treated with a standard course of acupuncture for breast pain, using paravertebral segmental points, trigger points, plus contralateral L14 on the non-lymphoedematous arm. She experienced an episode of galactorrhoea six days following the first treatment and during the second treatment. She had not previously lactated for four years. CT and MRI of the brain revealed no focal abnormality. acupuncture has been used in to promote lactation in the Traditional Chinese literature using the 'Tianzong' acupoint SI11. This acupoint coincided with a trigger point over infraspinatus that was included in the neurophysiologically based acupuncture treatment. Quantitative analysis has shown an increase in the production of prolactin and oxytocin following acupuncture. These hormones are involved in the synthesis and release of milk from mammary glands respectively. This is the first report of galactorrhoea, in the contralateral normal breast, following acupuncture in a patient with breast cancer.- - - - - - - - - - ranking = 0.5keywords = lactation (Clic here for more details about this article) |
