Item Chondro-osseous Type Metaplastic Carcinoma of Breast(2015) Pourbagher, Aysin; Aslan, Hulya; Bolat, Filiz AkaItem Granulocytic sarcoma of finger: a case report(2016) Purbager, Aysin; Ozen, Merve; Aslan, Hulya; Tok, Sermin; Kocer, EmrahGranulocytic sarcoma is an extramedullary tumor of immature myeloid cells. Such tumors may be located in any part of the body. We report a case of isolated granulocytic sarcoma of finger; which, to our knowledge, is the first report of that localization. A thirty-year-old woman with acute myeloid leukemia (AML) presented with progressive swelling and onychoptosis at her right fourth finger. The distal phalanx was excised and the tumor turned out to consisted of atypical myeloid cells, infiltrating bone trabeculae. Despite its rarity, considering myeloid sarcoma of the finger as a possible diagnosis may prevent inappropriate treatment in leukemia patients.Item Magnetic resonance imaging findings of extraskeletal mesenchymal chondrosarcoma of wrist: a case report(2016) Pourbagher, Aysin; Aslan, Hulya; Bal, NebilExtraskeletal mesenchymal chondrosarcomas (EMC) are high grade malignant tumors that rarely involves wrist. Published reports about them are mostly based on conventional radiography, tomography and conventional magnetic resonance imaging (MRI) findings. We did not recognize any report of dynamic-contrast enhanced MRI so far. Herein, we present dynamic contrast enhanced and Diffusion Weighted MRI findings of a case with extraskeletal mesenchymal chondrosarcoma of the wrist. In conclusion, EMC might show peripheral enhancement at early arterial phase and restricted diffusion on MRI. The knowledge of the imaging spectrum of the EMC might help us suggesting the diagnosis.Item Quantitative elastography in differentiating benign and malignant breast lesions(2016) Purbager, Aysin; Pekoz, Burcak Cakir; Aslan, Hulya; Agildere, Ahmet Muhtesem; 0000-0003-4223-7017; 0000-0002-7138-246X; AAB-5802-2020; AAK-9104-2021Purpose: The purpose of this study was to evaluate the effectiveness of quantitative elastography in differentiating benign and malignant breast lesions that were detected by B-mode ultrasonography, to compare shear wave velocities of benign and malignant lesions, and to determine cut-off values differentiating malignant lesions from benign ones Material and Methods: In this prospective study we enrolled 254 breast lesions of 240 patients detected by B-mode ultrasonography, and underwent biopsy in our department. Shear wave elastography was performed to all lesions before biopsies. The patients who had radiotherapy or chemotherapy previously were not included. Elastography examinations were performed by one of the two radiologists specialising in breast radiology. The mean and median shear wave velocities, and standard deviation values were measured in meters/second. Both mean and median shear wave velocities were compared with histopathology results. Sensitivity, specificity, and the area under the curve were obtained by using a receiver operating characteristic curve analysis Results: The mean age of the patients, lesion size, mean and median shear wave velocities were significantly different between benign and malignant groups. The mean shear wave velocity of benign and malignant lesions were 3.59 +/- 1.2m/s and 5.59 +/- 1.9m/s, respectively. The cut-off value for the mean shear wave velocity was 4.08 m/s (71.6% sensitivity and 69.6% specificity) to differentiate malignant lesions from benign ones Conclusion: Quantitative elastography is an effective and complementary method making a significant contribution in differentiating benign and malignant lesions. In this respect, we believe that clinical usage of shear wave elastography should be generalized
