Krukenberg tumor, defined as metastatic adenocarcinoma to the ovary containing at least 10% signet ring cells, usually arises from the stomach but can also originate from other sites. We reviewed 17 metastatic breast carcinomas to the ovary with signet ring cells to potentially identify features indicative of mammary origin as opposed to other possible primary sites. The patients ranged from 41 to 76 (mean, 53.6) yr. Fourteen had a prior history of invasive breast carcinoma (invasive ductal carcinoma, 4; invasive lobular carcinoma, 3; adenocarcinoma not otherwise specified, 3; carcinoma with ductal and lobular features, 2; and unspecified carcinoma, 2) and metastases were identified 2 to 284 (mean, 79) mo after the original diagnosis...

OBJECTIVE: Ductal carcinoma in situ (DCIS) is a noninvasive malignant breast disease traditionally described as a precursor lesion to invasive breast cancer. With screening mammography, DCIS now accounts for approximately 20% of newly diagnosed cancer cases. DCIS is not well understood because of its heterogeneous nature. CONCLUSION: Studies have aimed to assess prognostic factors to characterize its risk of invasive potential; however, there still remains a lack of uniformity in workup and treatment...

This paper aims to 137 cases of breast malignant tumors confirmed by surgery and pathology were collected. All patients received ultrasound examination and were not treated by radiotherapy or chemotherapy before operation. The preoperative ultrasound images of breast cancer patients and postoperative pathological characteristics of paraffin sections were retrospectively observed. Ultrasound indicators included tumor size, shape, ratio of the longest/shortest dimension, edge of the spiculation and peripheral hyperechoic halo sign, internal echo types, micro calcification, posterior echo types, blood flow and signs of lymph node metastasis...

Fusion images of diffusion-weighted whole-body imaging with background body signal suppression and T2-weighted image (DWIBS/T2) demonstrate a strong signal for malignancies, with a high contrast against the surrounding tissues, and enable anatomical analysis. In the present study, DWIBS/T2 was compared with (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) for diagnosing cancer in the abdomen. Patient records, including imaging results of examination conducted between November 2012 and May 2014, were analyzed retrospectively...

BACKGROUND: Borderline risk lesions such as flat epithelial atypia (FEA) are increasingly being diagnosed on biopsy. The need for surgery is being debated. In this study, we determined the frequency of histological upgrade following a diagnosis of FEA on biopsy and evaluated potential predictive factors. METHODS: Retrospective review was done of 194 women who underwent biopsy of indeterminate lesions (total 195 lesions) that were diagnosed as FEA. The review covered a 10-year period...

Transforming growth factor (TGF)-β promotes epithelial-mesenchymal transition and cell invasion of cancer cells in part through the small GTPase RAC1. Since RAC1 can signal through reactive oxygen species (ROS), we probed the role of the ROS-producing NADPH oxidase (NOX) and p38 mitogen-activated protein kinase (MAPK) in mediating TGF-β1/RAC1-driven random cell migration (chemokinesis). Although the NOX isoforms NOX2, 4, 5, 6, and RAC1 were readily detectable by RT-PCR in pancreatic ductal adenocarcinoma (PDAC)-derived Panc1 and Colo357 cells, only NOX4 and RAC1 were expressed at higher levels comparable to those in peripheral blood monocytes...

Pancreatic ductal adenocarcinoma is the most common primary malignancy of the pancreas. The classic imaging features are a hypovascular mass with proximal ductal dilatation. Different pancreatic pathologies can mimic the imaging appearance of carcinoma including other tumors involving the pancreas (pancreatic neuroendocrine tumors, lymphoma, metastasis, and rare tumors like pancreatic acinar cell carcinoma and solid pseudopapillary tumors), inflammatory processes (chronic pancreatitis and autoimmune pancreatitis), and anatomic variants (annular pancreas)...

Transcription factor AP-2β (TFAP2B) regulates embryonic organ development and is overexpressed in alveolar rhabdomyosarcoma, a rare childhood malignancy. Gene expression profiling has implicated AP-2β in breast cancer (BC). This study characterizes AP-2β expression in the mammary gland and in BC. AP-2β protein expression was assessed in the normal mammary gland epithelium, in various reactive, metaplastic and pre-invasive neoplastic lesions and in two clinical BC cohorts comprising >2000 patients. BCs from various genetically engineered mouse (GEM) models were also evaluated...

INTRODUCTION: Atypical ductal hyperplasia (ADH) is a high-risk benign lesion found in approximately 1-10% of breast biopsies and associated with a variable incidence of carcinoma after surgical excision. The main goal of our study is to present our experience in the management and long-term follow-up of 71 patients with ADH diagnosed on breast biopsy. MATERIALS AND METHODS: Results of 3808 breast biopsy specimens from 1 January 2000 to 31 December 2005 were analyzed to identify all biopsies which resulted in a diagnosis of ADH...

Rib osteomyelitis is an infrequently occurring but important complication of breast implant surgery. Although prosthetic or surgical site infection (SSI) and rib osteomyelitis as separate entities are well described in the literature, only five cases of rib or sternal osteomyelitis related to implant placement have been reported globally. Historically patients who experience this complication have not demonstrated an identifiable prevalence of the traditional risk factors associated with SSI or rib osteomyelitis...

Morphological evaluation of tumor-infiltrating lymphocytes (TILs) in breast cancer is gaining momentum as evidence strengthens the clinical relevance of this immunological biomarker. TILs in the post-neoadjuvant residual disease setting are acquiring increasing importance as a stratifying marker in clinical trials, considering the raising interest on immunotherapeutic strategies after neoadjuvant chemotherapy. TILs in ductal carcinoma in situ, with or without invasive carcinoma, represent an emerging area of clinical breast cancer research...

Sentinel lymph node biopsy for ductal carcinoma in situ (DCIS) of the breast is not standard of care. However, nodal involvement for DCIS patients is reported. Aim of our study was to identify preoperative features predictive of nodal involvement in DCIS patients. We have retrospectively reviewed 175 patients with a preoperative diagnosis of DCIS following a vacuum-assisted breast biopsy, and undergoing surgery with sentinel node biopsy. Variables distribution was compared between patients upstaged to invasive cancer at final pathology and patients with a confirmed DCIS, and between positive vs negative sentinel node patients...

Mucocele-like lesions of the breast diagnosed on core biopsy are usually excised to exclude the possibility of partial sampling of an invasive mucinous carcinoma. The goal of this study was to correlate the pathologic and radiologic features of mucocele-like lesions to determine if excision is mandatory. Over a 16 year period we identified 32 patients with mucocele-like lesions diagnosed on 27 (84%) stereotactic and 5 (16%) ultrasound-guided core biopsies. The indications for core biopsy were: calcifications in 24 (75%), a mass in 7 (22%), and a mass with calcifications in 1 (3%)...

Myoepithelial tumors of the soft tissue are a rare tumor displaying myoepithelial elements and lacking obvious ductal differentiation. The rarity of these precludes any evidence-based consensus regarding optimal management. Nevertheless, the current approach to these lesions begins with amputation or complete excision. The efficacy of neoadjuvant or adjuvant radiation therapy or chemotherapy has not been established. Here, we present the first report to the authors' knowledge of neoadjuvant radiation therapy for the treatment of this rare soft tissue neoplasm and review the management and outcomes of published cases of myoepithelial carcinoma...

Phodopus sungorus papillomavirus type 1 (PsuPV1), naturally infecting Siberian hamsters (Phodopus sungorus) and clustering in the genus Pipapillomavirus (Pi-PV), is only the second PV type isolated from the subfamily of hamsters. In silico analysis of three independent complete viral genomes obtained from cervical adenocarcinoma, oral squamous cell carcinoma and normal oral mucosa revealed that PsuPV1 encodes characteristic viral proteins (E1, E2, E4, E6, E7, L1 and L2) with conserved functional domains and a highly conserved non-coding region...

Spindle cell ductal carcinoma in situ (DCIS) is a recently recognized subtype of DCIS, which is associated with a very rare and unique morphology. Although the histologic features have been relatively well described in a few reports, the cytologic features have not. Even though the distinction of this lesion from usual DCIS is not crucial clinically, it should be noted that this lesion might simulate the features of metaplastic carcinoma on fine needle aspiration cytology. Here, we report a case of spindle cell DCIS in a 45-year-old female, with the detailed cytologic features, both on conventional and liquid-based preparations, along with some useful immunohistochemical staining markers for the differential diagnosis...

BACKGROUND: Breast cancer is the most common malignancy affecting the Iraqi population and the leading cause of cancer related mortality among Iraqi women. It has been well documented that prognosis of patients depends largely upon the hormone receptor contents and HER-2 over expression of their neoplasm. Recent studies suggest that Triple Positive (TP) tumors, bearing the three markers, tend to exhibit a relatively favorable clinical behavior in which overtreatment is not recommended...

Objectives: There is little information regarding sentinel lymph node (SLN) frozen-section examination in patients with a history of ductal carcinoma in situ (DCIS). We evaluated the usage, clinical impact, and pathology resources used for SLN cryosectioning in mastectomy cases with a DCIS history. Methods: Mastectomies with SLNs submitted from 2012 to 2013 at a tertiary care center were analyzed. Medicare reimbursement was used to estimate pathology health care expenditures of intraoperative frozen sections...
