Breast carcinoma metastasis to the cheek: a case report.

Background: Breast carcinoma is a common tumor in women, but it rarely metastasizes to the oral region. Furthermore, metastases to the oral region occur mainly to the maxillary and mandibular bone and rarely to soft tissue.

Case Presentation: We describe a case of breast cancer metastasis to the buccal area.

Characterization of SCC type IV methicillin-resistant clones increased in Japanese hospitals.

Recently, the prevalence of staphylococcal cassette chromosome (SCC) type IV isolates, which are the major community-acquired methicillin-resistant (MRSA), have increased in Japanese hospitals. The aim of this study was to elucidate the detailed molecular epidemiological features of the SCC type IV clones in Japanese hospitals. When 2589 MRSA isolated from four hospitals in Tokyo, Japan between 2010 and 2014 were analysed, the proportion of SCC type IV overtook that of type II, which was the major type of hospital-acquired MRSA in 2014.
