The surgical management of phyllodes tumors (PTs) is still controversial. Some studies have suggested surgical margins ≥1 cm, but recent studies suggested that negative margins could be appropriate regardless of their width. To evaluate recurrence rates of PTs following surgery according to margins. Retrospective study of women who attended a tertiary breast cancer reference center between 1998 and 2010: 142 patients with a PT diagnosis, either at minimally invasive breast biopsy or at surgery, were identified...

Metaplastic carcinoma of the breast is a rare form of breast cancer. The aim of the present study was to investigate the imaging and pathological features of metaplastic carcinoma. The features identified on mammography and sonography were retrospectively reviewed in 13 women with metaplastic carcinoma of the breast. The results from the mammographs and sonographs were additionally evaluated using immunohistochemical staining for the expression of the estrogen receptor (ER) and progesterone receptor (PR), receptor tyrosine-protein kinase erbB-2 (CerbB-2) and P53...

Invasive apocrine carcinoma (IAC) of the breast is a rare subtype of breast malignancy. Its incidence is not well known, but it is approximately less than 1% to 4%. For these reasons, there are few reports and little information on the radiologic appearance of IAC. Furthermore, most of the case reports show malignant features which are similar to invasive ductal carcinoma (IDC). We present a rare case of IAC without typical malignant feature on mammography, and ultrasonography (USG). Imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT are also presented...

In this paper, we introduce a new radiomic descriptor, Co-occurrence of Local Anisotropic Gradient Orientations (CoLlAGe) for capturing subtle differences between benign and pathologic phenotypes which may be visually indistinguishable on routine anatomic imaging. CoLlAGe seeks to capture and exploit local anisotropic differences in voxel-level gradient orientations to distinguish similar appearing phenotypes. CoLlAGe involves assigning every image voxel an entropy value associated with the co-occurrence matrix of gradient orientations computed around every voxel...

The number of performed core biopsies of the breast as diagnostic workup is increasing in many European countries. We measured the intraobserver variability in pathological assessment of breast core biopsies. Furthermore, we studied potential modifiers of agreement between the assessments. Two hundred and fifty-six breast biopsies were evaluated twice in a blinded fashion by two pathologists. We calculated the observed and the chance-corrected (weighted) intraobserver agreement (kappa) using the B-categorization scheme (B1: normal or not interpretable, B2: benign, B3: benign but of uncertain biological potential, B4: suspicious of malignancy, B5: malignant)...

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a pathology that is usually diagnosed by accident during pathological examination of other breast lesions. PASH is an uncommon and benign tumoral lesion of the mammary stroma that can be pathologically mistaken for other tumours, such as phyllodes, fibroadenoma, and sometimes even angiosarcoma. We report the case of a 45-year-old woman with complaints of huge bilateral breast enlargement. This is a rare case of PASH presenting with gigantomastia and involving bilateral breasts and axillae simultaneously...

Carney triad is a rare syndrome that involves gastrointestinal stromal tumor (GIST), pulmonary chondroma and extra-adrenal paraganglioma. Patients presenting GIST and pulmonary chondroma account for 72.7% of all incomplete Carney triad cases. Clinically, it is mainly diagnosed by radiological images and pathological results. Some studies have elucidated the pathogenesis of Carney triad. Surgical resection is the preferred treatment for Carney triad. Generally speaking, the prognosis of patients with Carney triad has been satisfied...

OBJECTIVE: Magnetic resonance (MR)-guided vacuum-biopsy is technically demanding and may fail depending on target-lesion size or breast size, and location of lesions within the breast. We developed an MR-guided vacuum-assisted biopsy protocol that collects larger amounts of tissue, aiming at an at least partial or complete ablation of the target-lesion, just as it is intended during surgical (excisional) biopsy. Rationale is to avoid biopsy failures (false-negative results due to undersampling) by collecting larger amounts of tissue...

PURPOSE: To assess the diagnostic performance of readout-segmented echo-planar diffusion tensor imaging (DTI based on rs-EPI) for breast cancer and to determine the correlation between the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values obtained from DTI based on rs-EPI with prognostic markers of invasive breast cancer. MATERIALS AND METHODS: This retrospective study examined 80 pathologically proven breast lesions (22 benign and 58 malignant lesions) of 80 patients who underwent both diffusion-weighted imaging based on single-shot echo-planar imaging (DWI based on ss-EPI) and DTI based on rs-EPI with b-values of 0 and 1000...

: Breast flat epithelial atypia (FEA) often coexists with more aggressive pathology and excision is currently recommended when diagnosed by core needle biopsy (CNB). Recent studies suggest isolated FEA has a low association with carcinoma and may warrant close surveillance. A radiology database containing 2189 breast CNB was reviewed for isolated FEA or FEA in combination with atypical pathology. 79 patients had FEA. There were 48/79 with isolated FEA and 31/79 concomitant FEA with ADH, ALH, or LCIS...

To evaluate whether biopsy with vacuum-assisted biopsy (VAB) devices improves histologic underestimation rates of benign papillomas when compared to smaller bore core needle biopsy (CNB) devices. Patients with biopsy-proven benign papillomas with surgical resection or minimum 12 months follow-up were selected. Two breast pathologists reviewed all pathology slides of percutaneous and excisional biopsy specimens. Histologic underestimation rates for lesions biopsied with 10-12 Gauge (G) VAB were compared to those with 14G CNB...
