Since Oct. 1, 1983 until April 15, 1986, authors analyzed variable combined imaging diagnosis andhistopathologic correlation for confirmed 100 breast carcinoma among 2773 patients whom authors took care of them.1. Incidence of female breast carcinoma was 3.6% among 2773 patients who visited Yong Dong Severance Hospital, andoverall breast carcinoma occupied 29.7% among 337 confirmed breast diseases. 2. Prevalent cancer age for Koreanwomen breast carcinoma was ages between 40-49 years old(42%) however authors experienced 5% breast carcinoma amongtwentieth, and 22% breast carcioma among thirtieth. 3. Most common histopathologic type for breast carcinoma wasinfiltrating ductal carcinoma, scirrhous type(65). And most common breast parenchymal pattern related to breastcarcinoma was DY pattern(42%) followed by N1 pattern(25%). 4. Common film mammographic findings of breastcarcinoma were: ill defined bordered mass(68.4%), spiculation of mass(82.9%), vessel dilatation (59.8%) and thencalcification (44.4%). 5. Frequently visible ultramammographic findings were; irregular mass contour(79.6%),nonuniform internal echoes(87.0%), and posterior wall shadowing (86.0%). 6. Trials of above combined imagingmodalities for breast carcinoma resulted in his sensitivity of diagnosis(93.3%).

INTRODUCTION: Palpable breast tissue is so prevalent in studies of men and boys that some authors suggest differentiating it from clinically important gynecomastia. Understanding male breast problems present a great challenge to many physicians especially when there is no specific guidelines developed for men.

OBJECTIVES: This study aims to determine the demographic and clinical profile of male patients with breast problems consulting at Vicente Sotto Memorial Medical Center.

METHODOLOGY: This study is a review of 77 male patients seen at the breast center of Vicente Sotto Memorial Medical Center from April 1, 2001 to March 31, 2004. The clinical profile included the age, geographic origin, chief complaint, family history of breast cancer, clinical breast examination findings, attributes of the clinically palpable breast mass like number, size, consistency, laterality, location, associated breast pain and pain score, clinical diagnosis and final histopathologic report.

RESULTS: Within this time period, there were 2,669 consultations seen at the breast clinic. A total of 77 male patients, comprising 2.9 percent were seen at the clinic. The mean age of occurrence was 36.2 years old. The frequency distribution of breast problem is highest between the ages of 20 to 29 years old at 40.3 percent. In all of the 69 patients (89.61 percent) with clinically palpable mass, 66 patients (95.65 percent) only had a solitary mass while 3 patients (4.35 percent) had two masses. Forty-three (59.7 percent) of the masses were less than 2 centimeters in diameter. Only 1 (1.4 percent) of the 72 masses was fixed to the chest wall which turned out to be a soft tissue sarcoma while the rest (98.6 percent) were freely movable. Based on the final histopathologic results, gynecomastia was the most common diagnosis among patients subjected to fine needle aspiration biopsy and excisional biopsy.

CONCLUSION: Male breast problems are common in the third decade of life and among patients living the urban area like Metro Cebu. Male patients sought consultation due to problems of unilateral firm breast mass less than 2 centimeters in diameter located in the nipple-areola complex. The most common clinical diagnosis is that of gynecomastia which is supported by the final histopathologic result of the same condition.

Irregular hypoechoic masses in the breast do not always indicate malignancies. Many benign breast diseases present with irregular hypoechoic masses that can mimic carcinoma on ultrasonography. Some of these diseases such as inflammation and trauma-related breast lesions could be suspected from a patient's symptoms and personal history. Careful ultrasonographic examination and biopsy could help to differentiate these from malignancies.

OBJECTIVETo evaluate the diagnostic value of full-field digital mammography for breast cancer.

METHODSThe clinical data and mammograms of 230 patients with breast diseases between January 2008 and July 2008 were collected and reviewed. Craniocaudal (CC) and mediolateral oblique (MLO) view mammograms were performed in all patients before surgery. Three experienced radiologists in breast imaging assessment analyzed and classified all the mammograms according to breast imaging reporting and data system (BI-RADS). The sensitivity, specificity and accuracy were evaluated according to their pathological diagnosis. The reasons resulting in false-negative and false-positive diagnosis were also analyzed.

RESULTSOf the 238 samples, 130 had a malignant breast tumors and 108 cases of benign breast lesions. One hundred and nine of the 130 malignant breast tumors were invasive ductal carcinoma. Fifty-seven of the 108 benign breast lesions were breast adenosis. Masses or masses with microcalcification were the most frequently seen signs of the malignant tumors, accounting for 40.8% and 20.8%, respectively. The sensitivity, specificity and accuracy of FFDM in detecting breast carcinoma were 90.8%, 87.0% and 89.1%, respectively. The false-negative signs including negative X-ray finding (5 cases) and focal asymmetric densities (4 cases). The false-positive signs were masses with spiculate, indistinctive or lobulated margin leading to misdiagnosing the lesions as malignant tumors.

CONCLUSIONFull-field digital mammography (FFDM) is helpful in detection of breast cancers in women, with a higher sensitivity, specificity and accuracy, and has an important clinical application value.

PURPOSE: A significant improvement of imaging using synchrotron radiation (SR) is obtained by introducing phase-contrast technique. This technique provides greatly enhanced contrast and good soft tissue discrimination with high spatial resolution. The aim of this study was to observe microstructures of pathologic breast specimens including invasive breast cancer using phase-contrast technique with SR and to evaluate the feasibility of phase-contrast imaging in clinical application. METHODS: Phase-contrast microscopic image of normal breast tissue and the images of various breast diseases such as fibrocystic change, ductal carcinoma in situ, invasive ductal carcinoma, Paget's disease were obtained using hard X-ray microscopy with an 11.1 keV monochromatic beam from SR source and CsI (TI) scintillation crystal. Zernike phase-shifter was adapted for phase-contrast hard X-ray microscopy. The visual image was magnified 20 times by microscopic objective lens and captured using a full frame charge-coupled device camera. Obtained images were compared with corresponding histopathologic findings in the optical microscopy. RESULTS: The SR images of various breast diseases were obtained with a good contrast and high visibility by phase-contrast technique. It was possible to observe the microstructures with high spatial resolution down to the micron region. The characteristic features of each disease were consistent with the histopathologic findings of corresponding sample and the images of breast cancer and the other diseases were distinct from each other. CONCLUSION: Using phase-contrast technique, SR images of various breast diseases including breast cancer were obtained. These images were comparable with standard histopathologic findings and showed different features for each disease. The results suggest that phase-contrast microscopic imaging with SR has potential as a diagnostic tool and also its clinical application is feasible, especially in breast imaging.

The development of ectopic breast tissue is attributable to the failure of primitive mammary tissue to regress after the development of the mammary ridge, except at pectoral breast sites, and is most often evident in the axillae. Several benign and malignant breast diseases have been reported in ectopic axillary breast tissues. The most common cancerous pathology of ectopic breast tissue is invasive ductal carcinoma. Ectopic breast cancer presenting with simultaneous primary cancer of the pectoral breast is extremely rare. Herein, we report an invasive micropapillary carcinoma of an axillary ectopic breast, combined with a synchronous ductal carcinoma in situ in the contralateral pectoral breast of a 61-year-old woman.

The diagnosis of breast disease relies primarily on histopathological diagnosis of hematoxylin-eosin stained specimens. Recently, the histopathological diagnosis has been complemented to an extent by analyses of a growing array of immunohistochemical and molecular markers. Prohibitin is an evolutionarily conserved gene with homologues found in organisms ranging from yeast to man. Prohibitin has anti-proliferous activity and available data suggest a role in such diverse processes as normal cell cycle regulation, replicate senescence, cellular immortalization, and the development of sporadic breast tumors. In this study, the prohibitin protein was immunohistochemically stained in representative samples from 10 patients with fibrocystic diseases, 10 with fibroadenomas, 10 with ductal carcinomas in situ, and 33 with infiltrating ductal carcinomas of the breast. There were weaker expressions throughout the tissue in benign breast diseases, but there was stronger staining in the glandular epithelium of breast cancers than with the stromal components. The epithelial and the stromal prohibitin expressions were elevated in carcinomas in situ and in infiltrating ductal carcinomas. However, the expression was most notable in infiltrating ductal carcinomas. There was no correlation between the prohibitin protein and the histologic grade or the TNM stage in breast cancer(p<0.05). These results show that imunohistochemical staining of prohibitin can be used as a diagnostic biomarker in breast cancer.

Cathepsin D is a protease which is known to facilitate invasion and metastasis of breast carcinoma. Overexpression of cathepsin D is associated with poor clinical outcome and biologic aggressiveness of the breast cancer. We underwent immunocytochemical assay(ICA) for cathepsin D in fine needle aspiration cytology(FNAC) specimens from the breast carcinoma and benign breast diseases. In FNAC specimens cathepsin D was expressed in 21(42.9%) out of 49 cases of invasive ductal carcinoma, whereas negative result was observed in all 15 cases of benign breast diseases including 7 fibroadenomas, 6 fibrocystic diseases, and 2 benign ductal hyperplasias. Among the 11 FNAC specimens from ductal carcinoma in situ(DCIS), cathepsin D was expressed in 3 cases(27.3%). In FNAC specimens immunocytochemistry for cathepsin D showed positive result in 24 out of 60 carcinomas(sensitivity, 40%) and negative result in 15 out of all 15 benign breast diseases(specificity, 100%). No significant correlation was noted between cathepsin D expression in FNAC specimen and clinicohistological characteristics of the breast carcinoma, such as hormone receptors and cell differentiation. In conclusion, ICA of cathepsin D in FNAC specimens thought to be a good adjunct to differentiate malignancy from benign breast diseases.

Male Breast cancer is an uncommon disease with an incidence of I per cent of all breast cancers. Male breast cancer usually appears as a small mass with well-defined contour which is eccentrically located in relation to the nipple on mammogram. We report a case of breast cancer in a 51-year-old man with mammographic appearance of large hyperdense mass with nipple inversion and axillary lymphadenopathy, gray-scale sonographic finding of homogeneous solid mass and mu Itiple tumor vessels with in the mass on color Doppler ultrasound.

Pediatric breast disease is uncommon, and primary breast carcinoma in children is extremely rare. Therefore, the approach used to address breast lesions in pediatric patients differs from that in adults in many ways. Knowledge of the normal imaging features at various stages of development and the characteristics of breast disease in the pediatric population can help the radiologist to make confident diagnoses and manage patients appropriately. Most breast diseases in children are benign or associated with breast development, suggesting a need for conservative treatment. Interventional procedures might affect the developing breast and are only indicated in a limited number of cases. Histologic examination should be performed in pediatric patients, taking into account the size of the lesion and clinical history together with the imaging findings. A core needle biopsy is useful for accurate diagnosis and avoidance of irreparable damage in pediatric patients. Biopsy should be considered in the event of abnormal imaging findings, such as non-circumscribed margins, complex solid and cystic components, posterior acoustic shadowing, size above 3 cm, or an increase in mass size. A clinical history that includes a risk factor for malignancy, such as prior chest irradiation, known concurrent cancer not involving the breast, or family history of breast cancer, should prompt consideration of biopsy even if the lesion has a probably benign appearance on ultrasonography.
