This article examines the clinical presentation of ocular metastasis from an infiltrating lobular breast carcinoma. We examined a conjunctival biopsy from a 69-year-old woman who developed unilateral conjunctival inflammation together with a neurotrophic corneal ulcer and proptosis. Infiltrating lobular breast carcinoma (ILBC) was diagnosed using routine histology and immunohistochemistry. She had a past history of a hormone receptor-positive infiltrating ILBC 11 years ago with cutaneous and diffuse osteoblastic metastases, and she was kept under treatment with lezotrol...

Growing evidence indicates that microRNAs (miRNAs) play critical roles in the initiation and progression of breast carcinoma (BC) and are promising diagnostic biomarkers. In the present study, we aimed to identify a multi-marker miRNA pool with high diagnostic performance for BC. We collected miRNA expression profiles of BC samples and normal breast tissues from The Cancer Genome Atlas (TCGA) and screened differentially expressed miRNAs by conducting two‑sample t-tests and by calculating log2 fold-change (log2FC) ratios...

BACKGROUND: Both ovarian/breast cancers are the most prevalent hormone-associated gynecological-cancers, where uncontrolled cellular proliferations/genetic-errors are noticed. The cancer-antigen125 (CA125), which we assessed presently is an important biomarker in the early detection/monitoring of this disease-pathogenesis. METHODS: Serum/tissue CA125 was measured by solid-phase-Enzyme-linked-immunosorbent-assay in women with ovarian/breast tumors of different types (epithelial/non-epithelial; benign/borderline/malignant)/stages...

Germ-line mutations in BRCA genes have been shown to predispose patients to breast cancer. Studies have suggested that p53 alteration is a necessary step in tumorigenesis in BRCA carriers. Our previous study showed p53 alteration in morphologically normal/benign breast luminal cells in sporadic breast cancer patients, the so-called "breast p53 signature". Here, we studied p53 status in 66 BRCA1/2 carriers' breasts; 29 patients with breast carcinoma (2 patients with bilateral breast carcinomas) and 37 without...

Apocrine breast carcinomas were evaluated for the expression of components of the growth hormone-releasing hormone (GHRH) autocrine/paracrine pathway: GHRH and its receptors (GHRH-R), as mammary apocrine carcinomas and epithelium seemed to be uniformly positive for GHRH-R in a pilot study. The apocrine phenotype was determined on the basis of hematoxylin-eosin morphology and a congruent immunohistochemical profile (estrogen receptor negativity, androgen receptor and gross cystic disease fluid protein-15 positivity)...

BACKGROUND: The purpose of this study was to determine the impact of revised ASCO/CAP 2013 HER2 guidelines on the clinical practice of pathologists and oncologists. MATERIALS AND METHODS: Retrospective analysis of 1739 patients with invasive breast carcinoma who underwent reflex HER2 (fluorescence in situ hybridization [FISH]) testing, using both 2007 and 2013 guidelines (2007-2014). RESULTS: Using 2013 guidelines, 255 (15%; 95% confidence interval [CI], 13%-16%) cases were classified as HER2(+) as opposed to 186 (11%; 95% CI, 9%-12%) by 2007 guidelines (odds ratio [OR] 1...

Opsoclonus myoclonus syndrome (OMS) is a rare, neurological condition affecting 1 in 10 000 000 people annually. Opsoclonus, defined as involuntary rapid, multivectorial oscillations of the eyes, together with ataxia and myoclonus are usually present. OMS may be paraneoplastic: often associated with occult neuroblastoma in childhood and with breast carcinoma or small cell lung carcinoma in adults. Other aetiologies include viral or toxic agents. The pathogenesis is thought to be immune mediated. A 37-year-old woman with previous inflammatory cranial mononeuropathies was admitted for elective dilatation and curettage (D&C)...

Here we report the identification and characterization of a novel high molecular weight isoform of tropomyosin, Tpm4.1, expressed from the human TPM4 gene. Tpm4.1 expression is down-regulated in a subset of breast cancer cells compared with untransformed MCF10A breast epithelial cells and in highly metastatic breast cancer cell lines derived from poorly metastatic MDA-MD-231 cells. In addition, patients with invasive ductal breast carcinoma show decreased TPM4 expression compared with patients with ductal breast carcinoma in situ, and low TPM4 expression is associated with poor prognosis...

PURPOSE: To explore the correlation between tumor-infiltrating immune cell subsets and breast cancer prognosis. MATERIALS AND METHODS: Specimens of 102 patients with invasive ductal carcinoma of the breast were analyzed for immune-related markers (CD8, CD20, FOXP3 and CD68). The number of positive cells in the 3 most highly stained intratumoral stroma areas of the primary tumor was counted. The mean number was calculated and used to divide patients into 2 groups for each marker (CD8-high/CD8-low, CD20-high/CD20-low, FOXP3-high/FOXP3-low, and CD68-high/CD68-low)...

Breast carcinomas have been classified from the molecular point of view into four major groups (Luminal A, Luminal B, HER2 and triple negative). However, these groups are not homogeneous and there is a need to establish subcategories that can be identified by immunohistochemistry (IHC), to better predict prognosis and carry out treatments that are more effective. This study was conducted in 354 patients diagnosed with invasive ductal breast carci- noma. The expression of 22 molecules was analyzed by tissue matrices and the results obtained were compared with molecular classes defined by IHC, according to the expression of estrogen receptor (ER), progesterone receptor (PR) and HER2, and the overall survival...

BACKGROUND: T regulatory cells (Tregs) are known to negatively control immune response. The frequency of these cells was inversely correlated with clinical outcomes of breast cancer. CD19(+)CD24(hi)CD38(hi) cells also play a critical role in inflammation and autoimmune disease. However, their function in tumor immune response is less studied. In this study we aimed to determine the role of CD19(+)CD24(hi)CD38(hi) cells and some other clinicopathological variables in increasing the proportion of Tregs in breast cancer patients...

PURPOSE: Metastases are a common event in breast cancer. The expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) is essential for therapy and prognosis, and their conversion during disease progression potentially affects the treatment regimen. The aim was to analyze the estrogen, progesterone and HER-2 receptor expression in primary tumors and metachronous neck metastases from patients with breast cancer. METHODS: A retrospective analysis of 27 patients with breast cancer and metachronous neck metastasis was performed...

Adjuvant systemic treatments reduce the risk of breast cancer recurrence following the local treatment of primary stage I-III breast cancers. For patients with hormone-positive breast cancers receiving hormonal therapy, the risk of distant recurrence is under 20% and therefore, many patients may potentially be spared of chemotherapy. Consequently, several molecular signatures based on gene expression were developed to better determine which breast cancer patients would benefit from chemotherapy. We present the case of a 62-year-old woman diagnosed with an early stage hormone receptor-positive breast cancer that was treated with a partial mastectomy...

AIMS: GATA-binding protein 3 (GATA3) is a sensitive and relatively specific marker in breast and urothelial carcinomas. Its diagnostic utility in primary and metastatic breast cancers has been explored and confirmed. However, the relationship between GATA3 expression and different breast carcinoma intrinsic subtypes has not been specifically defined in the literature despite a few reports with a small number of cases. The aim of the current investigation is to clarify GATA3 expression among different histological subtypes and surrogate molecular breast carcinoma subtypes in a large series of cases...

The Epithelial-to-mesenchymal transition (EMT) is a cell-biological program that confers mesenchymal traits on carcinoma cells and drives their metastatic dissemination. It is, unclear, however, whether activation of EMT in carcinoma cells can change their susceptibility to immune attack. We demonstrate here that mammary tumor cells arising from more epithelial carcinoma cell lines expressed high levels of MHC-I, low levels of PD-L1 and contained within their stroma CD8+ T cells and M1 (anti-tumor) macrophages...

INTRODUCTION: Paragangliomas are neuroendocrine tumors arising from chromaffin cells located in sympathetic paraganglia. Mediastinal paragangliomas are extremely rare and can be classified as functional or non-functional according to their ability for secreting catecholamines. Patients can be asymptomatic and the diagnosis is usually incidental. Complete surgical resection remains the standard of care for paragangliomas. PRESENTATION OF CASE: We present a 44-year-old woman with a functional mediastinal paraganglioma incidentally found during the perioperative imaging workup for a diagnosed breast carcinoma...

Importance: Although the increased incidence of second primary malignant neoplasms (SPMs) is a well-known late effect after cancer, few studies have compared survival after an SPM to survival of the same cancer occurring as first primary malignant neoplasm (PM) by age. Objective: To assess the survival impact of SPMs in adolescents and young adults (AYAs) (15-39 years) compared with that of pediatric (<15 years) and older adult (≥40 years) patients with the same SPMs...

Although most human cancers display a single histology, there are unusual cases where two or more distinct tissue types present within a primary tumor. One such example is metaplastic breast carcinoma, a rare but aggressive cancer with a heterogenous histology, including squamous, chondroid, and spindle cells. Metaplastic carcinomas often contain an admixed conventional ductal invasive or in situ mammary carcinoma component, and are typically triple-negative for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 (HER-2) amplification/overexpression...
