OBJECTIVE Phyllodes tumor is a rare fibroepithelial neoplasia of the breast. Tumors are classified according to the histological criteria as benign, borderline, malignant groups. Criteria used to discriminate benign/malignant cases are stromal cytological atypia, stromal hypercellularity, mitotic rate, stromal overgrowth, and tumor margins. We designed this study retrospectively to see the vali...

Differentiating between malignant and benign masses using machine learning in the recognition of breast ultrasound (BUS) images is a technique with good accuracy precision, which helps doctors make correct diagnosis. The method proposed this paper integrates Hu’s moments analysis tumor. extracted features feed k-nearest neighbor (k-NN) classifier radial basis function neural network (RBFNN) to ...

background: the purpose of this study was to evaluate the results of stereotactic breast core needle biopsy in a tertiary breast center of tehran university of medical sciences. methods: patients who were candidates for mammography-guided stereotactic breast core biopsy from march 2011 to december 2013 were included in this study. stereotactic biopsy was performed by a dedicated prone hologic m...

Breast cancer is the most frequent disease in women, with one every 19 women at risk. fifth leading cause of death around world. The effective and efficient technique controlling development early identification. Mammography helps detection cancer, which saves lives. Many studies conducted various tests to categorize tumor obtained positive findings. However, there are certain limits. Mass cate...

PURPOSE A newly isolated mediastinal lymph node (LN) or a small pulmonary nodule, which appears during breast cancer surveillance, may pose a diagnostic dilemma with regard to malignancy. We conducted this study to determine which clinical factors were useful for the differentiation of malignant lesions from benign lesions under these circumstances. MATERIALS AND METHODS We enrolled breast ca...

Introduction: Different imaging modalities are used to evaluate salivary gland diseases, including tumors. Ultrasonography (US) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. The aim of this study was to evaluate the role of US in differentiating malignant from benign parotid tumors, in the context of previous controversy...

odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. we previously described orosomucoid-1 protein expression in odontogenic myxomas. however, whether orosomuc...

Meningioma is considered as a benign central nervous system tumor that accounts for approximately 18% of all brain tumors. About 5% of meningioma tumors are malignant and have more aggressive clinical signs and worse prognosis compared to benign tumors. Extracranial metastasis of meningioma is rare but in the case of occurrence, it is more prevalent in lung, liver and lymph nodes. Osseous metas...

Problem statement: Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. We propose an automatic feature extraction method in ultrasound elastography and echography for characterization of breast lesions. Approach: The proposed algorithm was tested on 40 pairs of biopsy proven ultrasound elastography and echography imag...
