Mucinous carcinoma (MC) of the breast forms part of the special type of breast cancers and is characterized histologically by aggregates or clusters of typically uniform cells floating within copious amounts of extracellular mucin (Bussolati and Sapino 2012). In order to qualify for a diagnosis of MC, the mucinous component should represent over 90% of the tumor (Harris et al. 2011).

Clinical Features

  • Incidence: Pure mucinous carcinoma (PMC) of the breast represents one of the rarest subgroups (Park et al. 2010) and accounts for approximately 2% of all breast carcinomas (Bussolati and Sapino 2012; Harris et al. 2011).

  • Age: Compared to conventional invasive breast carcinoma, PMC tends to affect an older population, typically in the postmenopausal age group (Park et al. 2010).

  • Sex: While MC of the breast primarily affects women, isolated case reports of male breast MC exist....
