1. Comparative analysis of the histopathological and epidemiological profile of ductal and lobular breast carcinomas diagnosed at the Hospital de Clínicas da Universidade Federal do Paraná during the period 2008-2013
RESUMO Introdução: O câncer da mama éa segunda causa de morte por câncer entre as mulheres em todo o mundo, e estuáis epidemiológicos podem auxiliar no entendimento dos seus mecanismos. Objetivos: Realizar um levantamento do número de casos dos carcinomas da mama diagnosticados em um período de seis anos. Método: Foi comparado com a literatura o

2. Magnetic resonance imaging of the breast: role in the evaluation of ductal carcinoma in situ
Resumo O carcinoma ductal in situ (CDIS) é uma lesão mamária precursora cujas células malignas não ultrapassam a membrana basal e possui risco de evolução para doença maligna. Sua detecção precoce aumentou com a mamografia de rastreamento. O objetivo deste estudo foi realizar uma revisão da literatura sobre as principais apresentações do CDIS na

3. Intraoperative imprint cytology versus histological diagnosis for the detection of sentinel lymph nodes in breast cancer treated with neoadjuvant chemotherapy
OBJECTIVES: To compare imprint cytology and paraffin section histology for sentinel lymph node detection in women with breast cancer treated with neoadjuvant chemotherapy. METHOD: A cross-sectional study and report of the sentinel lymph node statuses of 64 patients with breast cancer who underwent intraoperative imprint cytology and neoadjuvant chemotherap

4. Myiasis associated with an invasive ductal carcinoma of the left breast: case study
ABSTRACT Most breast cancers originate in the ductal epithelium and are referred to as invasive ductal carcinoma. In this study we report on the clinical procedures adopted to diagnose myiasis in association with infiltrating metastatic breast carcinoma in a female patient. A 41 years old woman came to the Federal Hospital of Andaraí complaining of intense

5. Ductal eccrine carcinoma of the axilla: a diagnostic pitfall
Abstract: Ductal eccrine carcinoma (DEC) is a rare sweat gland carcinoma with ductular differentiation. Clinically, it is characterized by a slowly growing, hardened plaque or nodule predominantly located on the head and neck. Histologically, DEC shares similar features to invasive breast carcinoma, thus causing great diagnostic challenges. We report a 69-ye

6. Breast-conserving surgery in locally advanced breast cancer submitted to neoadjuvant chemotherapy. Safety and effectiveness based on ipsilateral breast tumor recurrence and long-term follow-up
OBJECTIVE: To evaluate ipsilateral breast tumor recurrence after breast-conserving surgery for locally advanced breast cancer. METHODS: A retrospective observational cohort study was performed in patients with locally advanced breast cancer submitted to breast-conserving surgery after neoadjuvant chemotherapy based on an adriamycin-cyclophosphamide-paclita

7. Breast hamartoma: a clinicopathologic analysis of 27 cases and a literature review
OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, a

8. Immunohistochemical profile of high-grade ductal carcinoma in situ of the breast
OBJECTIVE: To determine the frequency of the immunohistochemical profiles of a series of high-grade ductal carcinoma in situ of the breast. METHODS: One hundred and twenty-one cases of high-grade ductal carcinoma in situ, pure or associated with invasive mammary carcinoma, were identified from 2003 to 2008 and examined with immunohistochemistry for estrog

9. Basal cytokeratin as a potential marker of low risk of invasion in ductal carcinoma in situ
OBJECTIVES: Biological markers that predict the development of invasive breast cancer are needed to improve personalized therapy for patients diagnosed with ductal carcinoma in situ. We investigated the role of basal cytokeratin 5/6 in the risk of invasion in breast ductal carcinoma in situ. METHODS: We constructed tissue microarrays using 236 ductal carc

10. Angiogênese, células-tronco neoplásicas CD34+ e sinvastatina em modelo de carcinogênese mamária induzida quimicamente / Angiogenesis, CD34+ cancer stem-cells and simvastatin in a chemically induced mammary carcinogenesis model
Breast cancer is the most common malignancy and the leading cause of death from cancer among females worldwide. Despite all the research and all the progress achieved so far, the morbidity and mortality due to this cancer remains high in patients at advanced stages. Recently, it was described a new model of carcinogenesis in which stem cells (SC) could be re

11. Genomic instability at the 13q31 locus and somatic mtDNA mutation in the D-loop site correlate with tumor aggressiveness in sporadic Brazilian breast cancer cases
OBJECTIVE: Genomic instability is a hallmark of malignant tissues. In this work, we aimed to characterize nuclear and mitochondrial instabilities by determining short tandem repeats and somatic mitochondrial mutations, respectively, in a cohort of Brazilian sporadic breast cancer cases. Furthermore, we performed an association analysis of the molecular findi

12. Tipos especiais histológicos de carcinomas da mama : perfil imunoistoquímico com ênfase na classificação molecular / Histological special types of breast carcinomas : immunohistochemical profile with emphasis on molecular classification
Most invasive breast carcinomas are classified as invasive ductal carcinoma, not otherwise specified (IDC-NOS), while approximately 25% are defined as special histological types (HST). These HST of breast carcinomas are categorized into at least 17 distinct pathological entities. Most studies in the literature regarding the molecular classification (luminal
