ObjectiveTo estimate the coverage of opportunistic mammography screening performed via the Brazilian Sistema Único de Saúde (SUS, Unified Health Care System), at the state and regional level, in 2013.Materials and MethodsThis was an ecological study in which coverage was estimated by determining the ratio between the number of mammograms performed and the expected number of mammograms among the population of females between 50 and 69 years of age. The number of mammograms performed in the target population was obtained from the Outpatient Database of the Information Technology Department of the SUS. To calculate the expected number of mammograms, we considered 58.9% of the target population, the proportion that would be expected on the basis of the recommendations of the Brazilian National Cancer Institute.ResultsIn 2013, the estimated national coverage of mammography screening via the SUS was 24.8%. The mammography rate ranged from 12.0% in the northern region to 31.3% in the southern region. When stratified by state, coverage was lowest in the state of Pará and highest in the state of Santa Catarina (7.5% and 35.7%, respectively).ConclusionThe coverage of mammography screening performed via the SUS is low. There is a significant disparity among the Brazilian states (including the Federal District of Brasília) and among regions, being higher in the south/southeast and lower in the north/northeast.

“…NEBC appears hypodense on mammography, as round or irregularly shaped masses with variable margins either speculated, indistinct, circumscribed, or obscured [14]. On ultrasonography, such tumors may present as either morphologically irregular solid lesions or lesions with a cystic component, with ill defined margins and increased vascularization [11]. In the present report, the tumor had speculated margins.…”

“…The 2003 World Health Organization (WHO) histologic classification of tumors of the breast and female genital organs defined NECB as breast carcinoma with more than 50% of the cell population expressing these neuroendocrine markers. Furthermore, the diagnosis of primary neuroendocrine carcinoma of the breast can be established when either an in situ component is found or extramammary sites are excluded [ 4 5 ]. In 2012, the WHO histologic classification was upgraded and these tumors were divided into three subtypes: neuroendocrine carcinoma, well-differentiated; neuroendocrine carcinoma, poorly-differentiated/small cell carcinoma; and invasive breast carcinoma with neuroendocrine differentiation [ 6 ].…”

Primary Neuroendocrine Carcinoma of the Breast with Clinical Features of Inflammatory Breast Carcinoma: A Case Report and Literature Review

et al. 2015

Primary neuroendocrine carcinoma of the breast (NECB) is a very rare type of invasive breast carcinoma. Most NECBs appear on breast imaging as solid masses of varied shapes and margins, and have worse clinical outcomes than does invasive ductal carcinoma, not otherwise specified. However, there have been no reports to date regarding NECB with features of inflammatory breast carcinoma. Here, we describe the clinical, radiol-ogic, and pathologic findings of the first reported case of primary NECB presenting as inflammatory breast carcinoma. The patient complained of diffuse right breast enlargement and erythema. Mammography identified severe breast edema and axillary lymphadenopathy. Ultrasound detected an irregular, angular, hypoechoic mass with dermal lymphatic dilatation. On magnetic resonance imaging, the mass had rim enhancement and the entire right breast showed heterogeneous enhancement with malignant kinetic features. Pathology identified the mass as a primary NECB with positive for synaptophysin, CD56, estrogen and progesterone receptors.
