1/16. Karyotypic and histopathologic findings in an accessory breast.Accessory breasts are a clearly hereditary anomaly. They enlarge during pregnancy and lactation as a consequence of high blood levels of estrogen and prolactin, and are subject to all the diseases that occur in normal breasts. cytogenetic analysis was performed on one accessory breast. The monossomy of chromosome 16 was the main alteration found in this material. Nonscheduled cell proliferations may produce chromosome alterations, most of them with no clinical meaning. When relevant genes are altered, major proliferations or progression to malignancy may occur.- - - - - - - - - - ranking = 1keywords = lactation (Clic here for more details about this article) |
2/16. 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 = 1keywords = lactation (Clic here for more details about this article) |
3/16. New bilateral microcalcifications at mammography in a postlactational woman: case report.A 33-year-old woman with a strong family history of breast cancer who was referred for mammography 5 weeks after completing lactation was found to have new diffuse bilateral microcalcifications in the breast ducts. Contrast material-enhanced magnetic resonance imaging of the breast showed bilateral patchy areas of abnormal enhancement. Large-core needle biopsy showed diffuse calcifications within expanded benign ducts in a background of lactational change, without evidence of malignancy. To the authors' knowledge, these calcifications have not been previously reported and are possibly related to milk stasis or apoptosis associated with lactation.- - - - - - - - - - ranking = 7keywords = lactation (Clic here for more details about this article) |
4/16. Bilateral galactocele in a male infant: a rare cause of gynecomastia in childhood.A galactocele is a rare benign breast lesion usually occurring in females during or following lactation. These lesions are a rare cause of breast enlargement in infants and children. In this article we present a 10 month-old boy who was admitted with a two-month history of bilateral progressive breast enlargement, and diagnosed as having galactocele. Our purpose was to emphasize the importance of galactocele as a benign condition in the differential diagnosis of gynecomastia in childhood.- - - - - - - - - - ranking = 1keywords = lactation (Clic here for more details about this article) |
5/16. Giant hamartoma of the breast.hamartoma of the breast is a rare clinico-pathologic entity. Its clinical diagnosis can be extremely difficult; however, diagnosis is not difficult when it is made on the basis of a combination of radiologic and pathologic features. Its differential diagnosis includes a circumscribed fibrocystic mass, fibroadenoma, lipoma, cystosarcoma phylloides, and various carcinomas. A high index of suspicion is mandatory. In this study, we report a case of giant hamartoma of the breast in a young postlactational female patient, including treatment of the tumor by excisional biopsy and correction of the resulting breast deformity by mastopexy. Clinical, radiologic, and pathologic features are discussed.- - - - - - - - - - ranking = 1keywords = lactation (Clic here for more details about this article) |
6/16. Raynaud's phenomenon of the nipple: a treatable cause of painful breastfeeding.Maurice Raynaud first described the vasospasm of arterioles in 1862, and Raynaud's phenomenon is now felt to be common, affecting up to 20% of women of childbearing age. Raynaud's phenomenon has been reported to affect the nipples of breastfeeding mothers and is recognized by many lactation experts as a treatable cause of painful breastfeeding. In 1997, Lawlor-Smith and Lawlor-Smith reported 5 women with Raynaud's phenomenon associated with breastfeeding, but there are few other case reports, and none report the possible relationship between Raynaud's phenomenon of the nipple and previous breast surgery. We report 12 women who breastfed 14 infants, all of whom were seen in 1 pediatric practice and 1 lactation consultation center in san francisco, california, within the past 3 years. Of the 12 women, 11 were seen between June 2002 and May 2003. All women suffered from extremely painful breastfeeding, with symptoms precipitated by cold temperatures and associated with blanching of the nipple followed by cyanosis and/or erythema. Poor positioning and poor attachment or latch may cause blanching of the nipple and pain during breastfeeding, but 10 of the 12 mothers were evaluated by experienced lactation consultations, who were sure that inappropriate breastfeeding techniques were not contributing factors. Because the breast pain associated with Raynaud's phenomenon is so severe and throbbing, it is often mistaken for candida albicans infection. It is not unusual for mothers who have Raynaud's phenomenon of the nipple to be treated inappropriately and often repeatedly for C albicans infections with topical or systemic antifungal agents. Eight of our 12 mothers and their infants received multiple courses of antifungal therapy without relief before the diagnosis was made. To diagnose Raynaud's phenomenon accurately, additional symptoms such as precipitation by cold stimulus, occurrence of symptoms during pregnancy or when not breastfeeding, and biphasic or triphasic color changes must be present. All our mothers experienced precipitation of symptoms by cold stimuli and demonstrated biphasic or triphasic color changes, and 6 of the 12 experienced symptoms during pregnancy. Interestingly 3 of 12 mothers also reported a history of breast surgery, including 1 mother who had a fibroadenoma removed and 2 who had breast-reduction surgery. The association between breast surgery/implants and autoimmune disease, including Raynaud's phenomenon, has been discussed extensively, but the association of Raynaud's phenomenon of the nipple during breastfeeding has not been reported previously. Given the small numbers in the study, it is uncertain as to whether this may be a precipitating factor in developing Raynaud's phenomenon. Treatment options include methods to prevent or decrease cold exposure, avoidance of vasoconstrictive drugs/nicotine that could precipitate symptoms, and pharmacologic measures. There are reports in the lay press of the use of herbal medicines, aerobic exercise, and dietary supplements, but because most women with painful breastfeeding require immediate relief of the pain to continue breastfeeding successfully, it is important to offer a treatment plan that will alleviate the pain quickly. nifedipine, a calcium channel blocker, has been used to treat Raynaud's phenomenon because of its vasodilatory effects. Very little of the medication can be demonstrated in breast milk and thus is safe to use in breastfeeding mothers. Of the 12 mothers in our series, 6 chose to use nifedipine, and all had prompt relief of pain. Only 1 mother developed side effects from nifedipine. Pediatricians and lactation consultants should be aware of this treatable cause of painful breastfeeding and should specifically question their patients, because most mothers will not provide this information to the breastfeeding consultant. Prompt treatment will allow mothers to continue to breastfeed pain free while avoiding unnecessary antifungal therapy.- - - - - - - - - - ranking = 4keywords = lactation (Clic here for more details about this article) |
7/16. Postlactational microcalcifications.A case of postlactational microcalcifications is reported. A 42-year-old woman presented for screening mammography 2 months after completion of breast-feeding. Comparison to her pregravid screening mammogram revealed the appearance of multiple groups of indeterminate microcalcifications bilaterally (BIRADS IV). She underwent bilateral stereotactic core biopsies of representative areas, yielding benign pathology. There have been anecdotal accounts and five reported cases of lactational microcalcifications in the radiology literature. We discuss the possible etiologies as well as implications of this mammographic finding.- - - - - - - - - - ranking = 6keywords = lactation (Clic here for more details about this article) |
8/16. Unilateral gestational macromastia--a rare disorder.Macromastia is the massive enlargement of the breast, unilateral or bilateral, disproportionate to the growth of the rest of the body. It is called gravid macromastia or gigantomastia of pregnancy when it occurs during pregnancy. It may or may not regress following parturition. Gestational macromastia is exceptionally rare. We report a 28-year-old female with gigantomastia of the left breast. She presented at four months post-partum with painful massive enlargement of the left breast since the third month of pregnancy. The overlying skin was stretched out and showed multiple ulcers with foul smelling discharge. The nipple and areola were unremarkable. Simple mastectomy was done, as fine needle aspiration cytology was suggestive of phylloides tumour. The breast specimen measured 30 x 30 x 9 cm and was replaced totally by grey-white tissue involving all the resection margins. No normal breast tissue or fat was identified. Histopathology showed periductal as well as diffuse fibrosis, adenosis and lactational changes. No features of phylloides tumour or carcinoma were present and it was diagnosed as unilateral gestational macromastia.- - - - - - - - - - ranking = 1keywords = lactation (Clic here for more details about this article) |
9/16. Nipple pain, mastalgia and candidiasis in the lactating breast.During lactation, persistently sore nipples or shooting breast pain in the absence of local or systemic signs may be symptoms of C. albicans infection of the nipples and/or breast ducts. The nipple may be erythematous or fissured, but the appearance does not resemble oral or vaginal candidiasis. Case 1 is a woman with sore nipples following a course of antibiotics. Case 2 is a woman with severe shooting breast pain which was worsened by antibiotic treatment. Treatment included topical and oral antifungal treatment for the mother in conjunction with an 'anti-candida' diet. The infant's mouth was also treated to prevent reinfection.- - - - - - - - - - ranking = 1keywords = lactation (Clic here for more details about this article) |
10/16. Management of sub-areolar abscess and mammary fistula.Sub-areolar abscess is a form of chronic non-lactational mastitis often presenting in young women at the areolar margin as a recurring discharge or painful infection. Incision and drainage is inadequate and will be followed by recurrence unless the major duct leading from the abscess to the nipple is identified and laid open. Three cases are presented to illustrate this problem and its management.- - - - - - - - - - ranking = 1keywords = lactation (Clic here for more details about this article) |
