title: Rare breast malignancies and review of literature: A single centres experience.
abstract: BACKGROUND
  Breast cancer is a heterogeneous condition, with variants which are less common but still very well defined by the World Health Organization (WHO) classification. With the small number of cases each year large trials are difficult to perform. This series aims to discuss the rare breast malignancies encountered within a breast department and the evidence based approached to their management.
  
  
  METHODS
  Literature search of electronic databases via PubMed and the search engines Google/Google Scholar were used. Emphasis on keywords: breast cancer and the type of histology used to limit search. Searches were screened and those articles suitable had full text versions retrieved. The references to all retrieved texts were searched for further relevant studies.
  
  
  CONCLUSIONS
  Due to the rarity of some of these breast cancers, systematic evaluation of patient with detailed histopathology will aid accurate diagnosis and management. The series hopes to add the existing understanding of this small percentage of cases.
