BACKGROUND: Although identification of human epidermal growth factor receptor 2 (Her2) positive breast cancer represents one of the greatest advances over the past 3 decades, it has not been studied extensively on a national level. METHODS: The National Cancer Database is a joint project of the American Cancer Society and the American College of Surgeons and contains data on about 70% of the cancer cases in the United States. Data on Her2 have been collected since 2010 and was used for this study...

BACKGROUND: Minimally-invasive approaches are attractive alternative to standard craniotomy for large intracranial tumors with potentially lesser morbidity. In this report, we describe a sequential combination of two minimally-invasive surgical techniques to treat a large intracranial tumor. CLINICAL PRESENTATION: A 49year-old woman presented with a history of breast cancer and large left parietal metastasis with significant perilesional edema. This was initially managed by whole brain radiation therapy and stereotactic radiosurgery...

OBJECTIVES: Breast cancer is a heterogeneous disease consisting of distinct histopathological subtypes with different clinical outcomes. In this article, we identified the automated breast volume scanning (ABVS) and shear wave velocity (SWV) characteristics of different pathological types of breast carcinoma. METHODS: A retrospective review of both ABVS and SWV imaging of 118 consecutive breast masses was performed. The imaging features of both techniques were assessed with reference to histopathological results...

INTRODUCTION: Benign Phyllodes Tumours (PTs) are rare fibroepithelial neoplasms that resemble fibroadenoma. But unlike fibroadenoma, benign PT can recur and both stromal & epithelial components can progress to malignancy. Contrary to earlier belief that benign PT is a stromal neoplasm and possibly arises from fibroadenoma, more recent molecular studies have suggested that both stroma and epithelium can become neoplastic. Sometimes, benign PT can occur synchronously with fibroadenoma. Here histomorphologic analysis of eleven cases of benign PT are presented including some unusual features...

BACKGROUND: The urachus is a vestigial tubular structure that connects the urinary bladder to the allantois during early embryonic development. Urachal carcinoma develops in the urachus, which is an embryological remnant of the urogenital sinus and allantois. The estimated annual incidence of urachal carcinoma in the general population is 0.01% of all cancers in adults. Moreover, urachal carcinoma accounts for 0.34% to 0.7% of all bladder carcinoma cases. And breast metastasis is extremely rarer...

Invasive micropapillary carcinoma (IMPC), an aggressive variant of adenocarcinoma, is associated with a poor prognosis. Although IMPC has been reported to occur in various organs, pure IMPC has only been reported in the breast, pancreas and colon. There are no reports of IMPC of the esophagogastric junction (EGJ). According to previous reports on gastric IMPC, IMPC occupied, at most, 90 % of the whole tumor. IMPC is reported to occur least frequently in the gastric cardia. We herein report a rare case of pure IMPC of the EGJ...

MUC4 is a transmembrane mucin lining the normal colonic epithelium. The aberrant/de novo over-expression of MUC4 is well documented in malignancies of the pancreas, ovary and breast. However, studies have reported the loss of MUC4 expression in the majority of colorectal cancers (CRCs). A MUC4 promoter analysis showed the presence of three putative TCF/LEF sites, implying a possible regulation by the Wnt/β-catenin pathway, which has been shown to drive CRC progression. Thus, the objective of our study was to determine whether MUC4 is regulated by β-catenin in CRC...

BACKGROUND: Breast ultrasound findings regarding tumor margins are crucial in judging whether a tumor is malignant or benign. However, the relationships between the margins and clinicopathological characteristics remain largely unknown. In this study, we examined the clinicopathological characteristics of patients with invasive ductal carcinoma whose ultrasound images showed either well-defined and rough or indistinct margins. METHODS: Of all consecutive patients diagnosed with invasive ductal carcinoma at the Division of Breast and Endocrine Surgery of Tottori University Hospital from January 2012 to December 2014, 122 patients whose ultrasound images showed either "well-defined and rough" or "indistinct" tumor margins were included in this study...

Adenomas of the breast are rare benign tumors although single cases with malignant behavior have been reported. However, the genetic basis of these tumors is unknown. Employing targeted next generation sequencing of 50 cancer-related genes as well as Sanger sequencing, we profiled a cohort of 18 mammary adenomas comprising 9 ductal, 6 tubular, and 3 lactating adenoma. Missense mutations were detected in 8 of the 18 cases (44%). Specifically, five (56%) ductal adenomas and three (50%) tubular adenomas harbored mutated genes...

Salivary gland-type tumors have been rarely described in the thyroid gland. Mammary Analog Secretory Carcinoma (MASC) is a recently defined type of salivary gland carcinoma characterized by a t(12;15)(p13;q25) resulting in an ETV6-NTRK3 fusion gene. We report 3 cases of MASC involving the thyroid gland without clinical evidence of a salivary gland or breast primary; the clinico-pathologic characteristics are reviewed. Assessment for rearrangement of the ETV6 (12p13) locus was conducted by fluorescence in situ hybridization (FISH) on representative FFPE sections using an ETV6 break apart probe (Abbott Molecular, Des Plaines, IL, USA)...

Two cases of primary sebaceous lymphadenoma of the thymus are presented. The patients were a man and a woman 58 and 77 years old, respectively. The female patient had a history of breast carcinoma and on follow-up was identified to have an anterior mediastinal mass; the male patient did not have any history of malignancy, and the tumor was discovered during a chest radiographic evaluation when the patient presented with symptoms of fatigue, chest pain, and dyspnea. Histologically, both lesions were characterized by the presence of solid-cystic epithelial islands in a prominent lymphocytic background...

Epithelial-to-mesenchymal transition (EMT) plays an important role in the development of the invasive and metastatic potentials of breast cancer cells during progression. Human biliverdin reductase (hBVR), an enzyme in the heme metabolism pathway, is involved in hypoxia-induced renal tubular EMT. However, whether hBVR contributes to the EMT of breast cancer remains unclear. Here, we used breast cancer cell lines (MCF-7, T-47D) and normal breast epithelial cells (MCF-10A) to explore the potential role of hBVR in the EMT of breast cancer...

Tubular carcinoma is a subtype of invasive breast cancer that comprises 1 to 4 per cent of invasive breast cancers. Prior studies show nearly 100 per cent 15 year survival rate for tubular carcinoma compared to the 89.2 per cent five year survival of all breast cancers. These encouraging statistics beg the question should tubular cancers be treated as other invasive cancers, or can some patients be spared an invasive procedure or the side effects of adjuvant therapy? Fifty-seven cases of tubular carcinoma over 16 years were analyzed...

The concept of "precision medicine", where therapy is personalized to unique disease and host characteristics, is currently revolutionizing treatment strategies in oncology. A key point in this concept is the fact that several so-called "targeted drugs" may only be effective when tumors exhibit characteristic molecular features. This implies that companion diagnostic tests should be performed before treatment. There is evidence suggesting that the first step in predictive pathology is represented by morphology...

Adenoid cystic carcinoma (ACC) of the breast is a rare type of tumor. Our objective was to determine the clinicopathologic features of breast ACC. We reviewed slides of breast ACC reported during 12 years. Seven cases were identified. Age ranged from 38 to 59 years (mean = 47 years). Mean tumor size was 2.3 cm (range 1.2 to 4 cm). Histologically, dominant cribriform pattern was seen in 4 cases, solid in 2 and tubular in one case. Mitotic figures ranged from 2 to 22/10 HPFs. Grades I and II were seen in 3 cases each while 1 was grade III...

Mammary analogue secretory carcinoma (MASC) is a recently described tumor sharing the histologic, immunohistochemical, and molecular profile of secretory carcinoma of breast. We aimed to evaluate the morphologic and histochemical features needed/required for the diagnosis of MASC without adjunct of molecular analysis. Six retrospective cases suspicious for MASC and 5 prospective cases reported as MASC were included in the study. Molecular analysis of ETV6 by fluorescence in situ hybridization was performed at the University of Pittsburg, USA...

PURPOSE: The current study evaluated associative effects of breast cancer cells with the tumor microenvironment and its influence on tumor behavior. EXPERIMENTAL DESIGN: Formalin-fixed paraffin embedded tissue and matched protein lysates were evaluated from two independent breast cancer patient data sets (TCGA and MD Anderson). Reverse-phase protein arrays (RPPA) were utilized to create a proteomics signature to define breast tumor subtypes. Expression patterns of cell lines and normal breast tissues were utilized to determine markers that were differentially expressed in stroma and cancer cells...

Metastatic neuroendocrine neoplasms to the breast may show considerable morphologic overlap with primary mammary carcinomas, particularly those showing evidence of neuroendocrine differentiation, and may be misdiagnosed as such. Accurate distinction between these two entities is crucial for determination of appropriate clinical management. The histologic and immunohistochemical features of metastatic neuroendocrine neoplasms to the breast were studied and compared with the features of primary invasive mammary carcinomas with neuroendocrine differentiation, which served as controls...

BACKGROUND: Ectopic breast tissue, which includes both supernumerary breast and aberrant breast tissue, is the most common congenital breast abnormality. Ectopic breast cancers are rare neoplasms that occur in 0.3% to 0.6% of all cases of breast cancer. PATIENTS AND METHODS: We retrospectively report, using a large series of breast abnormalities diagnosed and treated, our clinical experience on the management of the ectopic breast cancer. In 2 decades, we observed 327 (2...
