Vascular tumors of the breast are rare and may pose a diagnostic challenge. Breast hemangioma is a very rare benign vascular neoplasm accounting for 0.4% of all breast tumors. It is most commonly detected as an incidental microscopic finding in biopsy specimens obtained for unrelated reasons. We describe here a very rare case of a sinusoidal breast hemangioma in a postmenopausal patient who presented with a palpable breast mass. A complete surgical resection was performed because the tumor exhibited atypical imaging features...

INTRODUCTION: Phyllodes tumors (PTs) are rare fibroepithelial tumors of the breast which are classified as benign, borderline, or malignant. Malignant PTs account for <1% of malignant breast tumors, and borderline tumors have potential to progress to malignant tumors. Metastatic recurrences are most commonly documented in bone and lungs. We report an extremely rare presentation of recurrent malignant PTs involving the brain, lung, lymph nodes, and bone. CASE: A 66-year-old female presented with a large breast mass...

Objective - Gynaecomastia is a benign proliferation of glandular tissue of the breast, however, it is an important clinical observation because it can be the first symptom of an underlying disease. Some controversy exists concerning the clinical importance of an in-depth investigation of men who develop gynaecomastia. We hypothesize that a thorough work-up is required in adult men with gynaecomastia. Design- All adult men (n=818) referred to a secondary level andrological department at Rigshospitalet in Copenhagen, Denmark in a four-year period (2008-2011) under the diagnosis of gynaecomastia (ICD-10: N62) were included...

BACKGROUND: Atypical hyperplasia (AH) and mammographic breast density (MBD) are established risk factors for breast cancer (BC), but their joint contributions are not well understood. We examine associations of MBD and BC by histologic impression, including AH, in a subcohort of women from the Mayo Clinic Benign Breast Disease Cohort. METHODS: Women with a diagnosis of BBD and mammogram between 1985 and 2001 were eligible. Histologic impression was assessed via pathology review and coded as non-proliferative disease (NP), proliferative disease without atypia (PDWA) and AH...

A 52-year-old woman visited our hospital with a chief complaint of a mass in the left breast. Palpation revealed a mass approximately 3 cm in diameter located on the outer aspect of the left breast. Breast ultrasound revealed a hypoechoic area with an indistinct border, which suggested breast cancer or mastitis. A needle biopsy revealed no evidence of malignancy, and granulomatous mastitis was diagnosed. Antibiotic therapy showed no improvement; therefore, we began prednisolone treatment for the patient. The mass diameter decreased over the subsequent 5 months after initiating this treatment, and we decreased the dose of prednisolone gradually...

Hepatocellular carcinoma related protein 1 (HCRP1), which is essential for internalization and degradation of ubiquitinated membrane receptors, is downregulated in several tumors and strongly affects the outcomes of cancer patients. It is reported the expression of HCRP1 is inversely related to epidermal growth factor receptor (EGFR) in breast cancer and lead to resistance to cetuximab in ovarian cancer. However, its exact mechanism in the progression of Hepatocellular carcinoma (HCC) remains unknown. Herein, HCRP1 expression and its clinical significance were examined in 101 HCC patients using immunohistochemistry...

Intraoperative frozen pathology is critical when a breast tumor is not diagnosed before surgery. However, frozen tumor tissues always present various microscopic morphologies, leading to a high misdiagnose rate from frozen section examination. Thus, we aimed to identify breast tumors using bioimpedance spectroscopy (BIS), a technology that measures the tissues' impedance. We collected and measured 976 specimens from breast patients during surgery, including 581 breast cancers, 190 benign tumors, and 205 normal mammary gland tissues...

BACKGROUND: Postmenopausal obesity is associated with increased circulating levels of androgens and estrogens and elevated breast cancer risk. Crown-like structures (CLS; microscopic foci of dying adipocytes surrounded by macrophages) are proposed to represent sites of increased aromatization of androgens to estrogens. Accordingly, we examined relationships between CLS and sex-steroid hormones in breast adipose tissue and serum from postmenopausal breast cancer patients. METHODS: Formalin-fixed paraffin embedded benign breast tissues collected for research from postmenopausal women (n = 83) diagnosed with invasive breast cancer in the Polish Breast Cancer Study (PBCS) were evaluated...

BACKGROUND: Molecular breast imaging (MBI) performed with (99m)Tc sestamibi has been shown to be a valuable technique for the detection of breast cancer. Alternative radiotracers such as (99m)Tc maraciclatide may offer improved uptake in breast lesions. The purpose of this study was to compare relative performance of (99m)Tc sestamibi and (99m)Tc maraciclatide in patients with suspected breast cancer, using a high-resolution dedicated gamma camera for MBI. Women with breast lesions suspicious for malignancy were recruited to undergo two MBI examinations-one with (99m)Tc sestamibi and one with (99m)Tc maraciclatide...

Digital whole slide imaging is an increasingly common medium in pathology, with application to education, telemedicine, and rendering second opinions. It has also made it possible to use eye tracking devices to explore the dynamic visual inspection and interpretation of histopathological features of tissue while pathologists review cases. Using whole slide images, the present study examined how a pathologist's diagnosis is influenced by fixed case-level factors, their prior clinical experience, and their patterns of visual inspection...
