Metaplastic breast cancer characterized by the presence of non-epithelial cellular elements is rare: representing less than 1% of breast carcinomas of typically highly aggressive, heterogeneous, chemo-resistant malignant tumors [1]. Low grade adenosquamous carcinoma [LGASC] is a rare variant of metaplastic carcinoma that is also characterized as a subgroup of triple negative breast cancers. Ini...
9 Five to ten per cent of all breast carcinomas are of hereditary origin. Many of them have been associated to 10 mutations in the BRCA1 and BRCA2 susceptibility genes. No ‘‘BRCA3’’ gene has been found to account for 11 the non-BRCA1/BRCA2 breast cancer (BRCAx) families, and BRCAx tumors are increasingly believed to 12 originate from multiple distinct genetic events. Phenotype studies have ques...
although most breast cancers are adenocarcinomas of the mammary gland, primary breast sarcomas may also arise from mammary gland mesenchymal tissue. sarcomas represent less than 1% of primary breast neoplasms. these tumors are at high risk of recurrence and are known to have poor prognosis. surgical resection is the primary treatment for these lesions and axillary lymph node dissection is not r...
PURPOSE This review aims to discuss the methodological aspects of dedicated molecular breast imaging (MBI) using 99mTc-sestamibi as radiotracer to guide biopsy of occult or unclear breast lesions on mammography (MG) and ultrasound (US) that are suspicious on MBI (BI-RADS criteria 4 and 5), including its advantages, limitations and future clinical applications. METHODS Literature search was pe...
Ductal breast cancer is a clinically heterogeneous disease; we investigate the correlation between tumor size, comedo necrosis, number of cell mitoses and axillary lymph node metastasis in ductal breast cancer. In this study, 104 ductal breast cancer specimens were collected and divided into 3 groups: T1 group (tumor size ≤ 2 cm), T2 group (2 < tumor size ≤ 5 cm) and T3 group (tumor size > 5.0 ...
Multifocal breast cancer (MFBC), defined as multiple synchronous unilateral lesions of invasive breast cancer, is relatively frequent and has been associated with more aggressive features than unifocal cancer. Here, we aimed to investigate the genomic heterogeneity between MFBC lesions sharing similar histopathological parameters. Characterization of different lesions from 36 patients with duct...
OBJECTIVE To evaluate the nature and imaging appearance of incidental enhancing breast lesions detected on a routine contrast-enhanced chest CT. MATERIALS AND METHODS Twenty-three patients with incidental enhancing breast lesions on contrast-enhanced chest CT were retrospectively reviewed. The breast lesions were reviewed by unenhanced and enhanced CT, and evaluated by observing the shapes, m...
Abstract Background Breast cancer is the most common malignant tumor among women. The mortality of patients could be mainly attributed to metastasis and spread breast distant sites. objective current study evaluate express role diffusion-weighted whole body imaging with background signal suppression (DWIBS) in detection osseous soft tissue metastatic lesions breast. Results prospective included...
Context: Breast an organ which is constantly under the influence of sex hormones, one frequent site neoplasm in human body. Benign breast diseases comprise a heterogeneous group lesions that present with varying symptoms or detected incidentally.Aims: To evaluate histopathological features benign and proliferative having potential to progress malignancy.Materials & Methods: All lumpectomy trucu...
Introduction: Nipple discharge is the third most common complaint of the breast diseases following the breast mass and the breast pain. The majority of the lesions causing pathological nipple discharge (PND) consist of non-palpable breast lesions (NPBLs). When non-operative diagnostic tools are inadequate to distinguish the diagnosis, the pathological duct should be removed to ...
