Granular cell tumor (GCT) of the breast is a rare clinical entity, and is believed to be of schwannian origin and to follow a benign clinical course. A 50-year-old woman presented with a slowly growing mass in the right breast. Fine needle aspiration cytology revealed a cellular smear containing isolated or clustered cells showing round to oval nuclei with abundant oncocytic granular cytoplasm. Nuclei showed a fine granular chromatin pattern and occasional small single nucleoli. Cell boundaries were poorly defined, and naked nuclei were frequently found, Histologically, the tumor showed features of typical GCT, and immunohistochemical staining findings strongly supported the diagnosis. The present study demonstrates that GCT of the breast can mimic malignant lesions of breast both clinically and radiologically. The recognition of its cytologic features and suspicion of this lesion would undoubtedly aid the correct diagnosis of mammary GCT.

Management innovation as a strategic alternative to create competitive advantages in the global market, is being actively progressed by conglomerates such as Samsung, LG and Toyoda as they cut a brilliant figure in the 21 century by using various innovation methods. However, the domestic railway sectors, in particular urban railway depots have neglected management innovation as they undertake Operation and Management in non-competitive settings of a corporate enterprise. This paper analyzes the critical success factors that have switched the most obsolete depots to a benchmark model for domestic railway depots based on the remodeling businesses undertaken in Gunja rolling stock maintenance office, Korea's first urban railway depot, along with 5S 6sigma program.

Purpose : To assess the usefulness of 3D-gradient echo dynamic contrast enhanced MRI (3D-DMRI) in the diagnosis of breast cancer and to determine the most useful parameter for this diagnosisMaterials and Methods : Using a 1.0T MR unit, (Magnetom, Sienens, Erlaugen, Germany), 3D-DMRI (TR/TE=30/12) with Gd-DTPA was performed in 38 cases of breast cancer, 22 of fibroadenoma, and in three normal volunteers. We retrospectively evaluated the findings according to the speed on dynamic study and maximal amount of contrast enhancement during the delayed phase;we calculated the three diagnostic parameters.Results : On conventional spin-echo T1- and T2-weighted imaes, there was no significant difference of signal intensity brtween benign fibroadenoma and breast carcinoma. Rapid contrast enhancement (within one minute) was benign in 35 breast cancer lesions (92.1%), but relatively low and slow contrast enhancement (after five minutes) was noted in three such lesions (7.9%). Gradual contrast enhancement was noted in 21 lesions of fibroadenoma (95.5%), but a moderate degree of rapid contrast enhancement (from three to five minutes) was noted in the other case (7.9%). of On the delayed enhanced phase of 3D-DMRI, the maximal amount of contrast enhancement showed no significant difference between fibroadenoma and cancer. On 3D-DMRI, an irregular, spiculated border, with high contrast enhancement was noted in all cases of breast cancer, in particular, irregular thick peripheral contrast enhancement with central necrosis was noted 11 cases (28.9%).Conclusion : For the diagnosis of breast cancer, 3D-DMRI is a useful technique. Among the diagnostic criteria of speed, maximal amount of contrast enhancement and morphology, morphologic change after contrast enhancement study was the most useful diagnostic parameter.

Purpose: The purpose of this study was to evaluate the utility of Gd-DTPA-enhanced dynamic MRI (DMRI) in earlydiagnosis and the assessment of disease processing in experimentally-induced crescentic glomerulonephritis (CGN)in rabbits. Materials and Methods: In six rabbits, CGN was induced by an injection of anti-glomerular basementmembrane Ab. A time-signal intensity curve (TSC) was obtained from DMRI on the day before, and at 1, 4, 7, 15, 45and 113 days after the induction of CGN. Sequential renal biopsies and blood sampling (serum creatinine) wereperformed on the same days, and the results of DMRI and TSC, were compared. Results: In normal kidneys, sequentialDMRI demonstrated the intratubular passage of Gd-DTPA as an inwardly migrating, thin, dark, band pattern. On days1 and 4, the thin dark band appeared but was poorly defined and TSC revealed a delay in peak time. On days 7 and15, movement of the band was seen to be weak and slow, and there was no centripetal migration. The maximal signalintensity of TSC was delayed, and the curves declined very slowly. On days 45 and 113, the dark band pattern wasvery weak and slow, and again there was no centripetal migration. Conclusion: GD-DTPA-enhanced DMRI may be ofvalue in the evaluation of disease processing and the severity of CGN.

Purpose: To compare 3D ultrasound (3D-US) with 2D ultrasound (2D-US) in terms of their usefulness and limitations in the diagnosis of breast masses. Materials and Methods: We obtained 2D and 3D US images of 37 breast lesions present in 20 cases of fibroadenoma, nine of cancer, and eight of fibrocystic disease proven in a total of 26 cases [fibroadenoma (n= 13), breast cancer (n= 9), fibrocystic disease (n=4)] by histologic examination, and by clinical evaluation and clinical evaluation with sonographic imaging in eleven. When comparing 3D and 2D-US images we had no prior information regarding detection rate according to the size of lesions, whether or not internal and boundary echo patterns could be interpreted, accurate differentiation between tumorous and non-tumorous lesions, or the accuracy with which benign and malignant tumors could be differentiated. Results: For lesions of 1 cm or less in diameter the detection rate of 3D-US was lower than that of 2D-US, but for lesions over 1 cm there was no difference between the two modalities. In fibroadenoma and breast cancer, 3D-US was more useful than 2D-US for the evaluation of both internal and boundary echo, but with fibrocystic disease and in the diagnosis of tumor/non-tumor, there was no significant difference. In breast cancer, however, 3D-US more accurately determined malignancy, and in fibroadenoma, because of the pseudospicule revealed by 3D-US, this modality was less exact in determining benignancy. Conclusion: In the evaluation of internal and boundary echo in breast mass diagnosis, 3D-US was more useful than its 2D counterpart. For lesions of 1 cm or less in diameter, however, the detection rate of 3D-US was low, and since in some benign cases a pseudospicule was apparent, the possibiliy of confusion with malignancy arose. For these reasons, the usefulness of 3D-US was limited. 목적: 유방 종괴의 진단에 있어서 2차원 초음파 진단과 비교하여 3타원 초음파진단의 유용성과 제한점을 알아보고자 하였다. 대상과 방법 : 37예의 유방종괴에 대하여 각각 2타원 초음파(HDI-3000, ATL, U.S.A.)와 3차원 초음파(Voluson 530D, Medison, Korea)를 이용하여 영상을 얻었다. 유방종괴는 섬유선종 20예, 유방암 9예. 및 섬유낭성질환 8예 등이었으며 섬유선종 13예, 유방암 9예, 및 섬유낭 성질환 4예는 병리조직학적으로 화친되었으며 나머지 11 예는 영상소견과 임상적 소견 및 초음파 결과를 토대로 진단하였다 전향적으로 사전 정보 교환 없이 각각 2타원 및 3타원 초음파 검사를 시행하여 병변의 크기에 따른 발견을, 내부에코 판별능, 경계에코 판별능. 종양과 비종양의 감별 진단에 있어서의 정확도, 및 종양에 있어서 양성과 악성진단의 감별의 정확도를 비교 분석하였다 결과: 크기가 1 cm 미만인 병변의 발견율은 2차원 초음파검사가 3차원 초음파검사보다 높았으나 1 cm이상의 병변은 2차원과 3차원 초음파검사간에 차이가 없었다 내부에코 판별능과 경계에코 판별능에서는 3차원 초음파검사가 2차원 초음파검사보다 섬유선종과 유방암에서는 더 유용하였으나 섬유낭성질환에서는 2차원 초음파검사와 큰 타이가 없었다 종양과 비종양의 감별진단의 정확도에서도 3차원 초음파검사와 2차원 초음파검사가 큰 타이를 보이지 않았으나 3차원 초음파는 유방암인 경우 악성도 예측에 있어서는 우수하였고 섬유선종의 경우에는. 3차원 초음파검사가 영상재건도중 발생하는 가성돌기로 인해서 2차원 초음파검사에 비해 양성도 예측률이 낮았다. 결론: 유방 종괴의 진단에 있어서 3타원 초음파진단은 2차원 초음파진단에 비하여 내부에코 판별능 및 경계에코 판별능에 있어서 유용한 소견을 보였다. 그러나 1 cm 미만의 작은 병변의 발견율이 낮고. 양성 종양의 일부에서 가성돌기 소견이 보여서 악성 종양과 혼돈을 일으킬 수는 있는 제한점이 있는 것으로 사료된다
