BACKGROUND Male breast cancer (MBC) is an uncommon disease that has been the focus of limited research. It is estimated that approximately 10% of men with breast cancer have a genetic predisposition, with BRCA2 being the most prevalent genetic mutation. Here we describe the case of MBC in a 64-year-old man who presented on physical examination a nodule in(More)
In recent years, the understanding of how DNA repair contributes to the development of innate and acquired immunity has emerged. The DNA damage incurred during the inflammatory response triggers the activation of DNA repair pathways, which are required for host-cell survival. Here, we reviewed current understanding of the mechanism by which DNA repair(More)
Germ-line mutation in CDH1 gene is associated with high risk for Hereditary Diffuse Gastric Cancer (HDGC) and Infiltrative Lobular Carcinoma (ILC). Although somatic CDH1 mutations were also detected in ILC with a frequency ranging from 10 to 56%, CDH1 alterations in more frequent infiltrative ductal carcinoma (IDC) appear to be rare, and no association with(More)
Salivary gland neoplasms are remarkable for their histological diversity and several studies point to their varied occurrence in the population. Clinical aspects were histologically assessed to determine possible associations and define parameters to differentiate benign and malignant neoplasms. The case files of patients diagnosed with epithelial salivary(More)
Oxidative DNA damage is considered to be a major cause of neurodegeneration and internal tumors observed in syndromes that result from nucleotide excision repair (NER) deficiencies, such as Xeroderma Pigmentosum (XP) and Cockayne Syndrome (CS). Recent evidence has shown that NER aids in removing oxidized DNA damage and may interact with base excision repair(More)
Cytogenetic studies in Brazilian population about childhood acute lymphoblastic leukemia (ALL), the most common childhood malignancy, are scarce. Moreover, Brazilian race is very heterogeneous and is made by the confluence of people of several different origins, from the original Native Brazilians, with the influx of Portuguese colonizers, Black African(More)
The Brazilian National Regulatory Agency for Private Health Insurance and Plans has recently published a technical note defining the criteria for the coverage of genetic testing to diagnose hereditary cancer. In this study we show the case of a patient with a breast lesion and an extensive history of cancer referred to a private service of genetic(More)
